Bob 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. bob is taking a combined total of 19 credit hours at the two schools. suppose that he is taking w credit hours at westside. write an expression for the combined total dollar amount he paid for his class fees.

In the problem we are given that:

Westside Community College

Class fees = $98 per credit hour

Amount of credit hours = w

Pinewood Community College

Class fees = $115 per credit hour

Amount of credit hours = 19 - w

Therefore the combined total dollar Bob is paying is:

Total payment = 98 * w + 115 * (19 – w)

Total payment = 98 w + 2,185 – 115 w

Total payment = 2,185 – 17 w
