D)

Answer 1

The answer is D) C(x) = 160x + 50

The 160 dollars is per course, but the 50 dollars is a one time fee.

Answer 2

Answer: Option D is correct.

Step-by-step explanation:

Since we have given that

the cost of tuition at Johnson Community College is $160 per credit hour

Let the credit hour be x

So ,the cost of tuition for x hours will be given by

$160x$

Now, we have also given that each student has to pay $50 in fees .

So, $ 50 will be to the cost of tuition for x hours i.e.

$160x+50\\\\C(x)=160x+50$

So, the cost function C for x credit hours taken by each student will be given by

$C(x)=160x+50$
