Question

Anna is ordering t-shirts for a community run. The company Anna is ordering from charges $12 per shirt and a shipping fee of $8. Based on this information, which function can be used to represent the relationship between the total cost, t, and the number of shirts Anna orders, m?
A. t=12m−8
B. t = 8m + 12
C. t = 12m + 8
D. t=8m−12

Answer 1

Answer:

D. t = 12m + 8

Step-by-step explanation:

This is the correct answer. I took the test.

Answer 2

The linear function that models the situation is:

$t = 12m + 8$

A linear function is modeled by:

$t(m) = am + b$

In which:

• a is the slope, which is the rate of change per unit m.
• b is the y-intercept, which is the "fixed" value.

In this problem:

• Charge of $12 per shirt, hence $a = 12$.
• Shipping fee of $8, hence $b = 8$

Thus, the relationship is modeled by:

$t = 12m + 8$
