Alan 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. Alan 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.
We are given that Alan takes classes at both Westside Community College, where class fees are $98 per credit hour, and Pinewood Community College, where class fees are $115 per credit hour.
If Alan is taking a total of 19 credit hours at the two mentioned schools, we are to write an expression for the combined total dollar amount he paid for his class fees.
Considering the fees per credit hour mentioned for each school, we can write the total payed fees as:
Step-by-step explanation: If w is hours at Westside, then (18-w) is the number of hours taken at Pinewood.
Cost to westside = 98w. Cost to Pinewood = 115(18-w).
Total cost = 98w + 115(18 - w) = 2070 - 17w.
[I guess there should be some constraints like 0 > w > 18]
I put it as "greater than" rather than "greater than or equal" because the problem states he takes classes at both schools, hence he has to take at least something at Westside, and similarly he has to take something at Pinewood so he would not take all 18 hours at Westside.
