Surf's Up charges $22 per hour to rent a surfboard and $8 per hour to rent a wetsuit. Marty and Cheryl paid a total of $240 to rent a surfboard and a wetsuit each for a few hours one day. Cheryl rented the surfboard and wetsuit for 2 hours less than Marty. The following equation represents this situation, where x represents the number of hours Marty rented the surfboard and the wetsuit.

22x + 8x + 22(x − 2) + 8(x − 2) = 240

What is the total amount Marty paid to rent the surfboard and wetsuit that day?

What is the total amount Marty paid to rent the surfboard and wetsuit that day?

anonymous · Answer

Marty's amount = $150, (5*22 = 110, not 44) & then add the 8*5 or 40 to make it 110 + 40 = $150
Cheryl's amount = $90
Check that the two amounts equal $240 ($150+$90 = $240)
