Q:

The function f(x) = 60x + 4 represents the amount of money Mike earns making custom tables. The function g(x) = 2x - 4 represents his upfront costs. Find (f/g) (4) to determine how much profit he will make from four tables. A) $8B) $61C) $240D) $244

A:
Answer:$244Step-by-step explanation:f(x) = 60x + 4 and g(x) = 2x-4We are told to find f(g=4), when Mike makes four tables.We have to put replace x in f(x) with the value g(x) when x is 4, like this: f(x) = 60x + 4 // Replace x with g(x) = 2x-4f(x) = 60(2x-4) + 4f(x) = (120x - 240) + 4 // Solvef(x) = (120*4 - 240) +4 // They tell us x=4f(x) = 480 - 240 + 4 = $244
