Answer:

f(5) = 104

Step-by-step explanation:

To find the value of f(5), we have to plug in 5 into our equation f(x) = 20x + 4.

f(5) = 20(5) + 4

Following our order of operations, we multiply first, then add to get our answer.  

f(5) = 20(5) + 4

f(5) = 100 + 4

f(5) = 104

The cost of 5 nights of camping is $104.
