The function t(x) = 2x + 4 determines how many cans of tomato sauce 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 tomato sauce. The function c(x) = 3x + 1. Solve for how much money must be spent when the crew is going to work 2 shifts.
The answer is $25. Since x equals the amount of shifts, and they tell you there is 2 shifts, you plug in 2 for x. Since it's a composite function you take t(2) (which is 8), and plug it in as x for c(x). After all the math the answer is 25.
