Answer:
The cost of producing 60 t-shirts is $495.
36 t-shirts will let the cost, C(x) = 303
Step-by-step 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
