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)
