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? Formulate an inequality and solve.

• 100 + 20x ≤ 250; They can boat for 8 hours.

• 100 + 20x ≤ 250; They can boat for 7 hours.

• 100 + 20x ≥ 250; They can boat for 7 hours.

• 100 + 20x ≥ 250; They can boat for 8 hours.

A children's birthday party at an indoor play center costs $50 to rent the space and $6.25 per child. Gina wants to spend no more than $100 on her son's fourth birthday party. Write an inequality for the number of children who can attend the birthday party, and solve the inequality.

• 50 + 6.25x > 100; x > 8

• 50 + 6.25x ≤ 100; x ≤ 8

• 50 + 6.25x < 100; x < 8

• 50 + 6.25x ≥ 100; x ≥ 8
