Amy 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. Amy is taking a combined total of 20 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.

Respuesta :

Answer:

Total fees=98w+115(20-w)

Step-by-step explanation:

From the information given, the combined total dollar amount she paid for her class fees would be equal to the fee per credit hour at Wetside for the number of credit hours she takes there plus the result of multiplying the fee per credit hour at Pinnewood for the number of credit hours Amy takes in that place. Also, it is important to take into account that the number of credit hours Amy takes at Pinnewood would be the result of subtracting the number of hours she takes at Westside from the combined total at the two schools that is 20. According to this, the expression for the combined total dollar amount she paid for her class fees is:

Total fees=98w+115(20-w), where:

w is the number of credit hours at Westside.
