Question

The turnout at a concert depends on the number of posters put up around town, so the turnout is a function of the number of posters that are hung. If this function is called T(p), use the formula below to compute T(9), the turnout at a concert that was advertised using 9 posters.

T(p) = 60p - p2

A. T(9) = 540
B. T(9) = 420
C. T(9) = 540 - 18
D. T(9) = 540 - 81

Answer 1

C. Because the number in front would be multiplied and the subtracted. Plug in 9 for p in every part.
