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
