b)

c)
c(x) = 110x
eliminate
d)
c(x) = 160x + 50

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

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.

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

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
