I use the formula y = 5x + 20 to figure out what I will pay to rent a moped when I go to Old Orchard Beach on vacation. x represents the number of hours that I rent the moped and y is the total cost. If the total cost to rent the moped was $75, how many hours did I rent the moped for?

• 7 hours

• 10 hours

• 11 hours

• 12 hours

y = -10x + 200
