Answer:
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)
