Question : 16 of 58

Marks: +1, -0

Maria plans to rent a boat. The boat rental costs

\$60

per hour, and she will also have to pay for a water safety course that costs

\$10

.Maria wants to spend no more than

\$280

for the rental and the course. If the boat rental is available only for a whole number of hours, what is the maximum number of hours for which Maria can rent the boat?

Your Answer:

Validate

Solution:

The equation

60h+10 ≤ 280,

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

h ≤ 4.5

. 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.
