Answer:
Abdul can rent the boat for at most 5 hours.
Explanation:
Let's call the number of hours Abdul rents the boat "t".
The cost of renting the boat without the discount coupon is $8 per hour, so the cost would be 8t dollars.
With the discount coupon, the cost of renting the boat would be 8t - 5 dollars.
We know that Abdul wants to spend at most $35, so we can write the inequality:
8t - 5 ≤ 35
Solving for t, we get:
8t ≤ 40
t ≤ 5
Therefore, Abdul can rent the boat for at most 5 hours.
