Question

The Mitchell family is renting a boat for the day. The boat rental has a flat fee of $100 plus $20 for each hour. They have to pay for a whole hour even if they are not out on the lake for a whole hour. For example, if they rent the boat for 3 and one-half hours, they have to pay for 4 hours.

If they want to spend $250 or less on the boat rental for the day, how many hours can they rent the boat? Write an inequality and solve.
A) 100 + 20x ≤ 250; They can boat for 7 hours.
B) 100 + 20x ≥ 250; They can boat for 8 hours.
C) 100 + 20x ≤ 250; They can boat for 8 hours.
D) 100 + 20x ≥ 250; They can boat for 7 hours.

Answer 1

7.5 and if you round it it would be 8 hours

Answer 2

The inequality has to be pointing at 250 since that’s the maximum of money they can spend so B and D are out. If you did the math and solved it, the answer would be 7.5 and rounded up which is 8 hours.
