Question

A function C(x) = 8x + 15 represents the cost C. in dollars of producing x, T-shirts for

the marching band.

what would be the cost of producing 60 t shirts?
find the number of t shirts if c(x)=303

Answer 1

The cost of producing 60 t-shirts is $495.

36 t-shirts will let the cost, C(x) = 303

Explanation:

If we producing 60 t-shirts, then we plug in 60 for the x, which x represents t-shirts for the marching band.

C(x) = 8x + 15

C(x) = 8(60) + 15

C(x) = 480 + 15

C(x) = 495

If the cost of the t-shirts is 303, we plug in 303 for the cost,C(x).

C(x) = 8x + 15

303 = 8x + 15

288 = 8x

x = 36
