A T-shirt design company charges your team an initial fee of $25 to create the team's design. Each T-shirt printed with your design costs an additional $8.
A. write a linear model that represents the Total cost of purchasing your team's T-shirt with your design as a function of the number of T-shirts.
B. your team has 35 members. If a T-shirt is purshased for every member. what would be the cost?
Answers
Answer:
Part A)
[tex]C(t)=25+8t[/tex]
Part B)
[tex]C(35)=\$305[/tex]
Step-by-step explanation:
We will let t represent the total number of t-shirts printed.
We are charged an initial fee of $25. So, for our linear model, our constant is 25. And each t-shirt printed costs an additional $8. So, for t t-shirts, it will cost an additional 8t dollars.
Part A)
So, from the above information, we can write the following function:
[tex]C(t)=25+8t[/tex]
Where C(t) is the total cost for t shirts.
The 25 represents our initial fee and the 8t represents the cost for t t-shirts.
Part B)
So, if we have a team of 35 members, we will need 35 t-shirts.
Then the total cost will be given by:
[tex]\begin{aligned}C(35)&=25+8(35)\\&=25+280\\&=\$305\end{aligned}[/tex]
So, it will cost a total of $305.
Last year, Jackson made 24 one-cup servings of chili for a school party. This year, he will make ten times the amount of chili that he made last year. If there are 4 cups in 1 quart and 4 quarts in one gallon, how many gallons of chili will Jackson make this year?
Answers
Answer: 15
Step-by-step explanation:
You have to multiply what Jackson made last year (24 cups) times 10 which equals 240. after that you do 240 divided by 4, which equals 60, and 60 divided by 4 again, which gives us the answer (15) (hope you could understand that) Also sorry for not answering in time!

Step-by-step explanation:

Answers
Answer:
True.
Step-by-step explanation:
Note the point values: (x , y) = (1 , 8) ∴ x = 1, y = 8
Plug in the corresponding numbers to the corresponding variables in the equation:
y > x + 5
(8) > (1) + 5
8 > 1 + 5
8 > 6
8 is greater than 6, ∴ y is greater than x + 5.

Answer:
m∠C = 54°, m∠CDB = 100°
Step-by-step explanation:
in ΔABC, m∠A= 37° and m∠B = 89°
The sum of all 3 angles in any triangle is 180° so
m∠C = 180-37-89 = 54°
m∠CDB = 180-80 = 100° because any line has a 180°angle
how do you solve -3 + 5 +6g =11 - 3g?
Answers
the add 3g to 6g to get 9g
then u have 2+9g=11
subtract 2 to both sides u get 9g=9
divide 9 u get 1=g hope I helped
Final Answer: [tex]g = 1[/tex]
Steps/Reasons/Explanation:
Question: How do you solve [tex]-3 + 5 +6g = 11 - 3g?[/tex]
Step 1: Simplify [tex]-3 + 5 + 6g[/tex] to [tex]6g + 2[/tex].
[tex]6g + 2 = 11 - 3g[/tex]
Step 2: Subtract [tex]2[/tex] from both sides.
[tex]6g = 11 - 3g - 2[/tex]
Step 3: Simplify [tex]11 - 3g - 2[/tex] to [tex]-3g + 9[/tex].
[tex]6g = -3g + 9[/tex]
Step 4: Add [tex]3g[/tex] to both sides.
[tex]6g + 3g = 9[/tex]
Step 5: Simplify [tex]6g + 3g[/tex] to [tex]9g[/tex].
[tex]9g = 9[/tex]
Step 6: Divide both sides by [tex]9[/tex].
[tex]g = 1[/tex]

solve the proportion 4/(x+1) = 3/(x+2)
Answers
Answer:
x = -5
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define
4/(x + 1) = 3/(x + 2)
Step 2: Solve for x
Cross multiply: 4(x + 2) = 3(x + 1)Distribute: 4x + 8 = 3x + 3Subtract 3x on both sides: x + 8 = 3Subtract 8 on both sides: x = -5Answer:
to solve a proportion, you cross multiply. so you take the numerator of the first one, and multiply it by the denominator of the second one. and then the denominator of the first one is multiplied by the numerator of the second one:
4(x+2)=3(x+1) (set them = and then use the distributive property)
4x+8 = 3x+3 (subtract 3x from both sides)
x +8 = 3 (subtract 8 from both sides)
x= -5 (the answer)
