a) Total purchase price for the bicycle is $19,145
b) The difference between the hire purchase price and the cost price for the bicycle is $2,825.50
c) The percentage of difference between the hire purchase price and the cost price for the bicycle is 17%
Percentage:
Percentage means a fraction or a ratio in which the value of whole is always 100.
Given,
A bicycle has cash price $16,319.50. It can be bought on hire purchase with a deposit of $6,900 and ten monthly installments of $1,224.50 each.
Here we need to following:
a) Purchase price for the bicycle
b) Difference between the hire purchase price and the cost price for the bicycle
c) Percentage of the cash price.
The total purchase price is calculated by adding the deposit and the ten month installment.
So, the total purchase price is,
=> 6900 + (10 x 1224.50)
=> 6900 + 12245
=> 19145.
Therefore, the total purchase price is $19145.
Now, the difference between the hire purchase price and the cost price for the bicycle is calculated as,
=> 19145 - 16319.50
=> 2825.50
So, the difference between the hire purchase price and the cost price for the bicycle is $2,825.50
Now, we have to calculate the percentage by using the following expression,
x% of 16,319.50 = 2825.50
x% = 2825.50/16319.50
x% = 0.1731
x = 17.31.
Therefore, there is 17% difference in the hire purchase price and the cost price for the bicycle.

A farmer has bushels to sell at a roadside stand. sells an average of
each day. Represent the total change in the number of bushels for sale after.
The total change in the number of bushels for sale is 64.1 bushels.
Given
A farmer has 160 bushels of apples to sell at her roadside stand. Every day, she sells around a 13 7/10 bushel.
Let us calculate the overall change in the number of bushels she has available for sale after 7 days.
137/10
Now we'll figure out how many bushels she'll sell in seven days.
7 x 137/10
95.9
In 7 days, the farmer will sell 95.9 bushels. To calculate our overall change, subtract this figure from the total number of bushels of apples.
165 - 95.9 = 64.1
Thus, a total of 64.1 bushels have been added to the amount of bushels available for sale.

Sarah spent 2 h more travelling by train than she did by bus. The train averaged 70 km/h and the bus 50 km/h. The total distance travelled was 740 km. How far did she travel by bus?
Answer:
250 km
Step-by-step explanation:
Sarah traveled a total of 740 km, 2 hours more at a speed of 70 km/h than at a speed of 50 km/h. You want to know how far she traveled at 50 km/h.
SetupThe relations between time, speed, and distance are ...
distance = speed × time
time = distance/speed
If 'd' represents the distance (km) Sarah traveled by bus (at 50 km/h), then the time (hours) required was ...
time = d/50
The time at 70 km/h is 2 hours more, and the total distance is ...
total distance = (distance at 50 km/h) + (distance at 70 km/h)
740 = d + 70(d/50 +2)
SolutionSimplifying the equation, we have ...
740 = 2.4d +140
600 = 2.4d . . . . . . . . subtract 140
d = 250 . . . . . . . . . . . divide by 2.4

Enter an equation in standard form that models the linear situation. A bathtub that holds 53 gallons of water contains 18 gallons of water. You begin filling it, and after 5 minutes, the tub is full.
The linear equation which represents the situation or the amount of water in the bathtub in terms of the number of minutes is y = 7x + 18.
What is a linear function?A straight line on the coordinate plane is represented by a linear function.
In another word, a linear function is a function that varies linearly with respect to the changing variable.
Let's suppose the number of minutes by x and the amount of water by y
As per the given question,
The amount of water (y) initially (x = 0) is 18 gallons.
The first point (0,18).
The amount of water (y) at x = 5 is 53 gallons.
The second point (5,53).
The linear equation is given as y = mx + c where m is the slope.
Slope m = (53 - 18)/(5 - 0) = 7
Substitute (0,18) →
18 = 7(0) + c
c = 18
So the equation become as,
y = 7x + 18.
Hence "The linear equation which represents the situation or the amount of water in the bathtub in terms of the number of minutes is y = 7x + 18".

Nathan sells jewelry and earns a 9.75% commission on every piece
he sells. How much commission would he earn on a bracelet that
sold for $220? Use any strategy
Answer:
$21.45
Step-by-step explanation:
You want to know the amount of a 9.75% commission on $220.
CommissionThe amount of the commission is the product of the commission rate and the sales amount to which it is applicable. A 9.75% commission on $220 will be ...
9.75% × $220 = 0.0975 × $220 = $21.45
Nathan would earn a commission of $21.45 on the sale.
__
Additional comment
We know that a 10% commission can be found by moving the decimal point on the sale amount. A 10% commission on $220 will be $22.
The commission rate of 9.75% is 1/4% less than 10%. 1/4% can be found in two steps: find 1%, then find 1/4 of that.
As with 10%, the 1% amount can be found by moving the decimal point. 1% of $220 is $2.20. One-quarter of that will be $2.20/4 = $1.10/2 = $0.55.
This is the amount we must subtract from the 10% value to make it be 9.75%.
The 9.75% commission amount is $22.00 -0.55 = $21.45.
(The point of using a strategy like this is that you can do the math mentally.)

A small publishing company is planning to publish a new book. The production costs will include one-time fixed costs (such as editing) and variable costs (such
as printing). There are two production methods it could use. With one method, the one-time fixed costs will total $49,631, and the variable costs will be $10.25
per book. With the other method, the one-time fixed costs will total $12,209, and the variable costs will be $23.75 per book. For how many books produced will
the costs from the two methods be the same?
Step-by-step explanation:
for both costs to be the same, the sum of the fixed and the variable costs must be the same.
so,
49631 + 10.25x = 12209 + 23.75x
37422 = 13.50x
x = 37422 / 13.5 = 2,772
the costs of both methods will be the same for 2,772 produced books.
Submit a 250 word minimum essay on the steps of solving for both the x and y intercept.
The essay will need to be in your own words of course, but the basic idea is to replace x with 0 and solve for y to get the y intercept. To get the x intercept, replace y with 0 and solve for x.
Here's an example
2x+5y = 10
Let's find the x intercept
2x+5y = 10
2x+5(0) = 10
2x = 10
x = 5 is the x intercept
Now we'll do the y intercept
2x+5y = 10
2(0)+5y = 10
5y = 10
y = 10/5
y = 2 is the y intercept
The x intercept is the location where the graph crosses the x axis. The y intercept is where the graph crosses the y axis.
Write the equation of the line in fully simplified slope-intercept form.
Step-by-step explanation:
a slope-intercept form :
y = ax + b
"a" is the slope, "b" is the y-intercept (the y-value when x = 0).
the slope is the ratio (y coordinate change / x coordinate change) when moving from on point on the line to another.
"b" we can read off the graph : when x = 0, then y = -5.
so, b = -5.
for the slope let's pick 2 points. your teacher has kindly marked already points with integer coordinates.
so, I pick (3, 1) and (4, 3).
x changes by +1 (from 3 to 4).
y changes by +2 (from 1 to 3).
so, the slope is
+2/+1 = 2/1 = 2
the equation is
y = 2x - 5
Answer: y=2x-5
Step-by-step explanation:
Choose two points on the graph: (0,-5) and (3,1)
The straight line equation is: y=mx+b
1)
[tex]\displaystyle\\\boxed {The\ slope\ m\ =\frac{y_2-y_1}{x_2-x_1} }[/tex]
[tex]\displaystyle\\x_1=0\ \ \ \ \ x_2=3 \ \ \ \ y_1=-5\ \ \ \ y_2=1\\\\ Hence,\\\\m=\frac{1-(-5)}{3-0} \\\\m=\frac{1+5}{3} \\\\m=\frac{6}{3} \\\\m=2\\\\Thus,\ y=2x+b\ \ \ \ \ (1)[/tex]
2)
To determine the coefficient b, take any of the two points,
for example, (0,-5), that is, x=0 y=5
Substitute these values into formula (1):
[tex]-5=2*0+b\\-5=0+b\\-5=b\\Thus,\ b=-5[/tex]
The result is y=2x-5
