The bowling lanes charge an hourly fee for bowling and $2 to rent shoes for the day. Gerry rented shoes and bowled for 2 hours and was charged $12.
 Which equation represents the cost, f(x), of bowling as a function of x, the number of hours of bowling?
 Of(x) = 4x + 3
 Of(x) = 2x + 2
 Of(x) = 5x - 2
 O f(x) = 5x + 2
