Question

Gina 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. Gina is taking a combined total of 13 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.

total paid = 213w

total paid = -17w + 1495

total paid = 98w + 115

total paid = 98 (13 - w) + 115

Answer 1

Answer: second option.

Step-by-step explanation:

Let be "w" the credit hours at Westside Gina is taking.

You know that class fees are $98 per credit hour at Westside, then the expression for the dollar amount she paid for her class fees at Westside is:

$98w$

Since she is taking a combined total of 13 credit hours at the two schools, the credit hours at Pinewood Gina is taking can be represented by this expression:

$13-w$

You know that class fees are $115 per credit hour at Pinewood, then the dollar amount she paid for her class fees at Pinewood can be expressed as:

$115(13-w)$

Therefore, the expression for the combined total dollar amount she paid for her class fees is:

$total\ paid=98w+115(13-w)\\\\total\ paid= -17w + 1495$
