The cost of a gym membership is a onetime fee of $140, plus a monthly fee of $40. Brendan wrote a $500 check to pay his gym membership for a certain number of months, including the onetime fee. How many months of membership did he pay for?
The correct answer is C.
After subtracting the onetime fee from the amount on Brendan’s check ($500 - $140), the remaining $360 goes toward the amount spent on monthly fees.
You can find the number of months of membership covered by the check by dividing the remaining $360 by the monthly fee of $40 per month, giving 9 months as the result.
You could also solve this problem by setting up and solving the equation:
Cost = Onetime Fee + (Monthly Fees) x Months
500 = 140 + 40m
40m = 500 - 140
40m = 360
m = 9
