Question: 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?
Answer: Step-by-step reasoning process: 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.
So the answer is 4.

Question: In Dana's senior high school class there were 200 students. 60% of the students were female, and 50% of the females were brunettes. If 50% of the female brunettes were under 5 feet tall, then how many female brunettes in Dana's high school senior class were under 5 feet tall?
Answer: Step-by-step reasoning process: In Dana's senior class, the 60% of 200 students is 0.6 * 200 = 120 female students. Fifty percent of the females, or 0.5 * 120 = 60 of the female students were brunettes. If 50% of the female brunettes were under 5 feet tall, then there were 60 * 0.5 = 30 female brunettes under five feet tall in Dana's senior class.
So the answer is 30.

Question: Jason spent 1/4 of his money and an additional $10 on some books. He then spent 2/5 of the remaining money and an additional $8 on some DVDs. If he was left with $130, how much money did he have at first?
Answer: Step-by-step reasoning process: Let X be the money Jason had at first. Jason spent 1 / 4 * X + 10 on books. Jason spent 2 / 5 * [X - (1 / 4 * X + 10)] + 8 on some DVDs. Jason has X - (1 / 4 * X + 10) - {2 / 5 * [X - (1 / 4 * X + 10)] + 8} = $130 left. X - 1 / 4 * X - 10 - 2 / 5 * X + 1 / 10 * X + 4 - 8 = $130. 9 / 20 * X - 14 = $130. X = $320.
So the answer is 320.

Question: Stormi is saving up to buy a bicycle. She washes 3 cars for $10 each. She mows 2 lawns for $13 each. If the bicycle she wants costs $80, how much more money does Stormi need to make to afford the bicycle?
Answer:
Step-by-step reasoning process: The total amount of money from washing cars is 3 * $10 = $30. The total amount of money from mowing lawns 2 * $13 = $26. The total amount of money Stormi makes is $30 + $26 = $56. Stormi still needs to make $80 - $56 = $24.
So the answer is 24.
