At a carnival, single rides cost $2 each, and all day ride passes cost $15. The total revenue for the day was $2,960.
 Which equation can be used to represent x, the number of single ride passes sold and y, the number of all day ride
 passes sold?
 O 2x + 15y = 2,960
 O 12x + 5y = 2,960
 O 15x + 2y = 2,960
 O 17x + 15y = 2,960
