Question

For a recently released movie, the function y = 119.67(0.61)x models the revenue earned, y, in millions of dollars each week, x, for several weeks after its release.

Based in n the equation, how much more money,in millions of dollars,was earned in revenue for week 3 than for week 5?

Answer 1

Given:
Function y = 119.67(0.61)x

x = week 3.

F(3) = 119.67(0.61)(3)
F(3) = 119.67*1.83
F(3) = 218.9961

x = week 5

F(5) = 119.67(0.61)(5)
F(5) = 119.67 * 3.05
F(5) = 364.9935
