Question

The function t(x) = x + 6 determines how many cans of soup a food truck needs to stock, where x is the number of shifts the crew is going to work in the truck. The crew uses c(t(x)) to find the amount of money to spend on soup. The function c(x) = 2x + 4. Solve for how much money must be spent when the crew is going to work 4 shifts.

Answer 1

First write cot(x) what it is and evaluate for 4

Answer 2

2x+4(x+6(4))

2*4+4(4+6(4))=120?
