Question

Carlos 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. Carlos is taking a combined total of 13 credit hours at the two schools. Write an expression for the combined total dollar amount he paid for his class fees.

Answer 1

x + y = 13

98x + 115y = z

Explanation:

Let x represent the time spent taking class in Westside community college

Let y represent the time spent taking class in Pinewood community college

Let z represent the combined total amount paid for the class fees.

The total combined time for the two school is given as:

x + y = 13.

For the combined total amount; we multiply the price for each school with the time spent on the school and sum them together.

Westside:
`98 * x = 98x`

Pinewood:
`115 * y = 115y`

The combined total amount represented as z is given as:

z = 98x + 115y
