PLEASE HELP ME ASAP

Mrs. Chambers orders math shirts for her math team. The design fee is $26 and the cost for each shirt is $18. She was emailed a coupon for $5 off of the design fee so she decided now is the best time to place the order. Which function shows the cost of the shirts if she uses the coupon? HINT: Remember f(x) means the same thing as y or the outcome or the total cost.

Question 2 options:

f(x)=5x+18


f(x)= 18x-26


f(x)= 18x


f(x)=18x+21

Answer 1

Answer: 18x+21

Step-by-step explanation: The function that shows the cost of the shirts if she uses the coupon is:

f(x) = 18x - 21

Step-by-step explanation:

The cost for each shirt is $18, and Mrs. Chambers is buying x number of shirts. So the cost of all the shirts would be 18x.

The design fee is $26, but she has a coupon for $5 off. So the new design fee would be 26 - 5 = $21.

Therefore, the total cost of the shirts and the design fee with the coupon would be 18x + 21, which is the same as f(x) = 18x - 21.
