Question

ANSWER PLEASE

Karen takes classes at both Westside Community College and Pinewood Community College. At Westside, class fees are $98 per credit hour, and at Pinewood, class fees are $115 per credit hour. Karen is taking a combined total of 16 credit hours at the two schools. Suppose that she is taking w credit hours at Westside. Write an expression for the combined total dollar amount she paid for her class fees.

Answer 1

y = 98w + 115(16 - w)

Explanation:

Let y = total amount paid

Let w = credit hours in Westside

Let 98w = Westside Fee

Let 115(16-w) = Pinewood

Then we get:

y = 98w + 115(16-w)

Now how did get 16 - w?

We got that by analyzing the problem. We have a total of 16 credit hours and w represents the number of hours at Westside. So we take the total of 16 hours and deduct it to the number of hours that Karen took in Westside.
