Answer: Total dollar amount = 98 w + 115 (18-w)

Step-by-step explanation:

Hi, the question is lacking the values and variables, the full question is:

Keiko 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. Keiko is taking a combined total of 18 credit hours at the two schools.

Suppose that he is taking w credit hours at Westside, Write an expression for a combined total dollar amount he paid for his class fees.

So, to answer this question we have to write an equation with the information given:

So, he has a total 0f 18 credit hours, and we only know that he is taking w credit hours at Westside. So, the credit hours that he is taking at pinewood is equal to 18-w.

The expressions are:

Westside cost: 98 w

Pinewood cost: 115 (18 - w)

If we add both expressions

Total dollar amount = 98 w + 115 (18-w)

Where w is the amount of credit hours he is taking at Westside.
