Question

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

Answer 1

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.
