Question 24 • (OC27) GEO-1206310-S2-Degele-VOL7006P

The number of rows in an auditorium can be represented by the function f(x) = 80x.The number of seats in each row can be represented by the function g(x) = x + 7.Which function represents the total number of seats, h(x) = f(x)g(x)?

Answer
A
h(x) = 136x
B
h(x) = 80x2 + 560x
C
h(x) = 80x + 560
D
h(x) = 80x2 + 560

Explanation

Multiply the number of rows by the number of seats in each row: h(x) = f(x)g(x) = 80x(x + 7). Distribute 80x to get h(x) = 80x² + 560x, which is choice B.
