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.​

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 hoursSo, the number of credit hours at Pinewood  =  19 - wThe 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)
