Debra is taking a combined total of 15 credit hours at the two schools. suppose that she is taking a credit hours at Westside. write an expression for the combined total dollar amount she paid for her class fees.

Answer 1

For this case we can create the following notation:

x= number of hours at westside

And we can create the following expression for the total amount of money that she paid like this:

A = 98 x+ 115 (15-x)

A= 98 x + 1725 -115x

A= 1725 - 17 x
