Given:
Initial amount (Base) = 15, 757
Rate of increase = 3.5% or 0.035 in decimal form
Find: new price and the price increase
Solution:
To be able to get the new price, we need to solve for the price increase first. To do that, we need to know what is 3.5% of the old price 15, 757. To calculate that, we will multiply 0.035 by 15,757.
[tex]0.035\times15,757=551.495\approx551.50[/tex]3.5% of 15, 757 is 551.50. This is the price increase of the car next year.
Hence, by next year, the new price will now be 15,757 + 551.50 = 16, 308.50.

A line passes through the point (-4,-6) and has a slope of 5/4. Write an equation in slope-intercept form for this line.
Answer:
y = [tex]\frac{5}{4}[/tex] x - 1
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
here m = [tex]\frac{5}{4}[/tex] , then
y = [tex]\frac{5}{4}[/tex] x + c ← is the partial equation
to find c substitute (- 4, - 6 ) into the partial equation
- 6 = - 5 + c ⇒ c = - 6 + 5 = - 1
y = [tex]\frac{5}{4}[/tex] x - 1 ← equation of line
How do I solve this exponential function using logarithms, it says if necessary you can round to the nearest hundredth, please show work!
The given equation is
[tex](x+7)=(2x-1)[/tex]At first, we have to isolate x on one side and the numerical term on the other side, then
Add 1 to both sides
[tex]\begin{gathered} x+7+1=2x-1+1 \\ x+8=2x \end{gathered}[/tex]Subtract x from both sides
[tex]\begin{gathered} x-x+8=2x-x \\ 8=x \end{gathered}[/tex]The solution of the equation is x = 8
The Smith’s and the Jones are neighbors. They both have a tax rate of 28.5 mills. The Smith’s house is assessed at $80,000. The Jones’ house is assessed at $67,000. How much more do the Smith’s pay in property tax?
Given
Tax rate = 28.5 mills
Smith's house is accessed at $80,000
Jones's house is accessed at $67,000
Property taxes are calculated by multiplying the assessed, taxable property value by the mill rate and then dividing that sum by 1,000.
The formula is given by:
[tex]Property\text{ tax levied on property = }\frac{mill\text{ rate }\times taxable\text{ property value}}{1000}[/tex]Property tax for the Smith's:
[tex]\begin{gathered} =\text{ }\frac{28.5\text{ }\times\text{ 80000}}{1000} \\ =\text{ 2280} \end{gathered}[/tex]Property tax for the Jones':
[tex]\begin{gathered} =\frac{28.5\text{ }\times\text{ 67000}}{1000} \\ =\text{ 1909.5} \end{gathered}[/tex]The extra amount the Smith's pay is the difference in the tax levied on Smith and Jones:
[tex]\begin{gathered} =\text{ 2280 - 1909.5} \\ =\text{ 370.5} \end{gathered}[/tex]Hence, the Smith's pay $370.5 more than the Jones'

use the data in the following table, which lists drive-thru order accuracy at popular fast food chains. Assume that orders are randomly selected from those included in the table. If two orders are selected, find the probability that they are both accurate. Complete parts (a) and (b) below.
a. Assume that the selections are made with replacement. Are the events independent?
The probability is __. The events __ (are, are not) independent.
(Do not round until the final answer. Round to four decimal places as needed.)
Answer:
a. If the selection is made with replacement, they are NOT independent because they affect each other.
b. The probability of selecting TWO accurate orders is .7157 and the events ARE independent.
Step-by-step explanation:
Add the accurate orders:
315+273+248+125=961
Add the inaccurate orders:
38+56+37+17=148
148/961=0.1540 probability of getting ONE inaccurate order
1.0-0.1540=0.846 probability of selecting ONE accurate order
0.846 * 0.846 = 0.7157 the probability of selecting TWO accurate orders
Therefore, the probability is .7157 and the events ARE independent.

Define a variable, set up an equation, then solve. the sum of two numbers 146. the larger number is 16 less than five times the smaller number. find both numbers.
The smaller number = 27
The larger number = 119
Explanations:Let the smaller number be x
Let the larger number be y
The sum of the two numbers is 146
x + y = 146..............(1)
The larger number is 16 less than five times the smaller number
y = 5x - 16.............(2)
Substitute equation (2) into equation (1)
x + (5x - 16) = 146
x + 5x - 16 = 146
6x = 146 + 16
6x = 162
x = 162/6
x = 27
Substitute the value of x into equation (2)
y = 5(27) - 16
y = 135 - 16
y = 119
The smaller number = 27
The larger number = 119

The second expression 1/(x^2 - 4x + 3) is equivalent to the given expression.
What are the equivalent expression?
Expressions that are equivalent do the same thing even when they have distinct appearances. When we enter the same value(s) for the variable, two algebraic expressions that are equivalent have the same value (s).
Consider the given expression,
((x + 3) / (x^2 - 2x - 3)) / ((x^2 + 2x -3)/ (x + 1))
We can write the expression as,
((x + 3) / (x^2 - 2x - 3)) x ((x + 1) / (x^2 + 2x -3))
Rewrite the equation x^2 - 2x - 3 and x^2 + 2x -3 as,
x^2 - 2x - 3 = x^2 - 3x + x - 3 = (x - 3)(x + 1)
x^2 + 2x - 3 = x^2 + 3x - x - 3 = (x + 3)(x - 1)
plug these values in the above expression, we get
((x + 3) / ((x - 3)(x + 1)) x ((x + 1) / ((x + 3)(x - 1))
After solving this, we get
1 / ((x - 3)(x - 1) = 1 / (x^2 - 4x + 3)
Therefore, the second expression is equivalent to the given expression.

You are the owner of Caché, a chain of women's clothing boutiques. Your state has a sales tax of 7%, and your city has an additional sales tax of 1.5%. Each quarter you are responsible for making these tax deposits to the city and state. Last quarter your stores had total revenue, including sales tax, of $271,250.
(a) 250000 of this revenue was sales and $11250 much was sales tax. (b) $11250 of sales tax should be sent to the city and $3750 sales tax should be sent to the state.
Let us assume that the total sales are $X.
According to the given situation, 7% is the sales tax and an additional state sales tax of 1.5% will be charges on the sales.
The total revenue including sales tax is $271250.
(a) Total revenue = sales + total sales tax
So, we can write,
X + X(7+1.5)% = 271250
Solving further,
X + X(8.5%) = 271250
X + 8.5X/100 = 271250
108.5X = 271250×100
X = 250000
Total sales is $250000.
Total sales tax is $(2710250-250000)
Total sales tax is $21250.
(b) Total sales is $250000.
Tax charges by city is 7%.
Using percentage formula,
Percentage of tax = Total tax amount/Total sales amount × 100
Putting all the values,
7 = Total tax amount/250000 × 100
Total tax amount = 7 × 2500
Total tax amount = 17500 dollars.
Total amount to be sent to the city is 175000$.
(c) Total sales is $250000.
Tax charges by city is 1.5%.
Using percentage formula,
Percentage of tax = Total tax amount/Total sales amount × 100
Putting all the values,
1.5 = Total tax amount/250000 × 100
Total tax amount = 1.5 × 2500
Total tax amount = 3750 dollars.
Total amount to be sent to the city is 175000$.

The function D = 25 + 0.3x represents the daily rental charge D (in dollars) for x miles driven. Is the domain discrete or continuous?
Hello!
First, let me explain the difference between discrete and continuous.
Discrete: only some numbers of the interval are on the input. For example, in the interval 1 - 10, consider only the integers.
Continuous: all the numbers of the interval are on the input. For example: in the interval 1 - 10, all values are considered (integers and decimals).
Knowing it, let's analyze your exercise:
The function D = 25 + 0.3x represents the daily rental charge D (in dollars) for x miles driven.
We can represent miles as integers and also decimals, right?
• 2 miles
,• 5.750 miles
So, it means that all values can be considered.
Answer:So, this is a continuous domain.

[tex]\begin{gathered} 2t^2-9t-18=0 \\ \\ (2t+3)(t-6)=0 \\ 2t+3=0 \\ \Rightarrow t=-\frac{3}{2} \\ \\ t-6=0 \\ t=6 \end{gathered}[/tex]6 is the realistic number of years (As we cannot have -3/2 years).
We conclude that they will break even in 6 years
b. The projected profit of a newly developed line of business is:
[tex]t^3[/tex]The total profit is now;
[tex]t^3+2t^2-9t-18[/tex]The company will break even with this new line of business as follows:
[tex]\begin{gathered} t^3+2t^2-9t-18=0 \\ (t+2)(t+3)(t-3) \\ t+2=0 \\ \Rightarrow t=-2 \\ t+3=0 \\ \Rightarrow t=-3 \\ t-3=0 \\ \Rightarrow t=3 \end{gathered}[/tex]We choose t = 3 (because we cannot have -2 years or -3 years)
The difference between this and the previous time is 6 - 3 = 3 years
