Answer explanation
The correct answer is 4. The equation 
, where h is the number of hours the boat has been rented, can be written to represent the situation. Subtracting 10 from both sides and then dividing by 60 yields 
. Since the boat can be rented only for whole numbers of hours, the maximum number of hours for which Maria can rent the boat is 4.
