Ravi 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 s115 per credit hour. ravi 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 the combined total dollar amount he paid for his class fees. total paid (in dollars) - 0 x 5 ?

98w +115(18-w)

Step-by-step explanation:

The fees per credit hour at Westside are $98.

The fees per credit hour at Pinewood are $115.

The total amount of hours is 18, this means the hours at Westside plus the hours at Pinewood add up to 18.

The problem asks us to name "w" the credit hours at Westside, therefore, the credit hours at Pinewood would be "18 - w"

Combining this information, we have that the combined total amount  he paid would be:

(Fee per hour at Westside)(hours at Westside) + (Fee per hour at Pinewood)(hours at Pinewood) = Total

⇒98w + 115(18 - w) = Total
