Donna 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. Donna is taking a combined total of 19 credit hours at the two schools.

suppose that she is taking w credit hours at westside. write an expression for the combined total dollar amount she paid for her class fees.

Expression for the combined total dollar amount she paid for her class fees is (2185 - 17 w)

Step-by-step explanation:

Let Donna is taking w credit hours at Westside.

Total combined credit hours at two schools = 19 hours

So, the number of credit hours at Pinewood = 19 - w

The per hour fees credit of Westside community college = $98

So, the total fees paid for w hours = w x Fees per hour

= w ($98) = $ (98w)

⇒The fees Donna pays at Westside community college = $ (98 w)

The per hour fees credit of Pinewood community college = $115

So, the total fees paid for (19 - w) hours = (19 - w) x Fees per hour

= (19 - w) ($115) = $ (2185 - 115 w)

⇒The fees Donna pays at Pinewood community college = $ (2185 - 115 w)

Hence, the total fees paid by Donna

= Fees at Westside + Fees at Pinewood

= $ (98 w) + $ (2185 - 115 w)

= $ (2185 - 17 w)

Hence, expression for the combined total dollar amount she paid for her class fees is $ (2185 - 17 w)
