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.

Question

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?

Question 1 options:

t=12m−8

t =12m +8

t = 8m + 12

t= 8m−12

Answer 1

To find the function that represents the total cost $t$ based on the number of shirts $m$ that Anna orders, we need to consider both the cost of the shirts and the shipping fee.

The company charges $12 per shirt, which means if Anna orders $m$ shirts, the cost for the shirts will be $12m$. In addition, there is a flat shipping fee of $8.

Therefore, the total cost can be represented by the equation:

$$t=12m+8$$

So the correct option is:

t = 12m + 8
