The Mitchells are renting a boat for the day. It costs $100, plus $20 for each hour. They have to pay for a whole hour even if they are not out there for a whole hour. For example if they boat for 3 and a half hours, they have to pay for 4 hours. They don't want to spend more than $250 for the day. How many hours can they 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.
