3 questions, please help!! It's like I'm invisible on here...

OpenStudy (anonymous):

The function t(x) = 3x + 5 determines how many cans of corn kernels 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 corn. The function c(x) = 2x + 3. Solve for how much money must be spent when the crew is going to work 3 shifts.

Would I set them equal to each other and solve x?

OpenStudy (anonymous):

Then plug it in?

OpenStudy (goformit100):

Yes you're correct^

OpenStudy (anonymous):

no

OpenStudy (anonymous):

No?

OpenStudy (anonymous):

c(t(x)) it means that the equation in t(x) should be replaced in the variable of c(x).... as i remember
