Flies are Betty's frog's favorite food. Every day the frog eats 2 flies. Betty puts the flies she finds in a bottle. In the morning Betty catches 5 flies inside a bottle, and in the afternoon she catches 6 more, but when she removes the lid, one escapes. Betty wants to gather the whole week's food for her frog. How many more flies does she need? Give the rationale and then the answer.
Let's think step by step. The frog eats 2 flies / day * 7 days / week = 14 flies a week. Betty catches flies in the morning and in the afternoon, for a total of 5 flies + 6 flies = 11 flies. But 1 fly escapes, leaving 11 flies - 1 fly = 10 flies. To get her frog's food for the whole week, Betty needs 14 flies - 10 flies = 4 more flies.. The answer is: 4.

James watched 2 episodes of Jeopardy and 2 episodes of Wheel of Fortune. Jeopardy is 20 minutes and Wheel of Fortune is twice as long. How many hours did he watch TV? Give the rationale and then the answer.
Let's think step by step. He watched 2 * 20 = 40 minutes of Jeopardy. Wheel of Fortune is 2 * 20 = 40 minutes each. So he watched it for 40 * 2 = 80 minutes. So he watched 40 + 80 = 120 minutes of TV. That means he watched 120 / 60 = 2 hours of TV.. The answer is: 2.

Happy Island has 60 turtles. This means there are 10 more than 2 times as many turtles on Happy Island as on Lonely Island. How many turtles are there on Lonely Island? Give the rationale and then the answer.
Let's think step by step. After subtracting 10 from the number of turtles on Happy Island, we get 60 - 10 = 50 turtles. Dividing this number by two, we find that the number of turtles on Lonely Island is 50 / 2 = 25 turtles.. The answer is: 25.
