Susan wants to rent a boat and spend at most $32. The boat costs $7 per hour, and Susan has a discount coupon for $3 off. What are the possible numbers of hours Susan could rent the boat?

Answer: the possible numbers of hours Susan could rent the boat is at most 5 hours

Step-by-step explanation:

Let x represent the number of hours

for which Susan could rent the boat.

The boat costs $7 per hour. This means that the cost of renting the boat for x hours is 7x.

Susan has a discount coupon for $3 off. This means that the total amount that she would pay for x hours is 7x - 3

Susan wants to rent a boat and spend at most $32. This would be expressed as

7x - 3 ≤ 32

7x ≤ 32 + 3

7x ≤ 35

x ≤ 35/7

x ≤ 5
