Question

15. A T-shirt company charges $4.25 to create the design for a T-shirt and $9.25 per

shirt
ordered. Diego's bill was $87.50. Circle the number that shows how many T-shirts
Diego ordered.
A 13
B 11
C 9
D 7

Answer 1

To solve this, i suggest coming up with an equation. Let “C” represent cost of production, and “x” represent number of shirts ordered.

C = 9.25x + 4.25

Since C is $87.50, plug that value in and find x.

87.5 = 9.25x + 4.25
83.25 = 9.25x
9 = x

Therefore, Diego ordered 9 shirts. I hope this helps.
