The function t(x) = 3x + 1 determines how many cans of green beans a food truck needs to stock on board, where x is the number o
mash [69]

Answer: The amount of money he must be spent when the crew is going to work 2 shifts is $11.

Step-by-step explanation:

Since we have given that

the function t(x)=3x+1 determines how many cans of green beans a food truck needs to stock on board , where x is the number of shifts the crew is going to work in the truck.

And the function c(x)= x+4

Since the crew uses c(t(x)) to find the amount of money to spend on green beans .

So, we will use "Composition of functions ":

c(t(x))=(3x+1)+4\\\\c(t(x))=3x+5

Since the crew is going to work 2 shifts , so our answer will be

c(t(2))=3(2)+5\\\\c(t(2))=6+5\\\\c(t(2))=11

Hence, the amount of money he must be spent when the crew is going to work 2 shifts is $11.
