Q: I have purchased 5 blue apples at the store. Suppose my neighbor gives me twice as many yellow apples as I have blue ones, and then I give my son 1/5 of the total number of apples; how many apples do I have now?
A: The number of blue apples is 5, and if you receive twice as many yellow apples as the number of blue apples, there will be 5 * 2 = 10 yellow apples. After receiving the yellow apples, you now have 10 yellow apples + 5 blue apples = 15 apples. When you give 1 / 5 of the total number of apples to the son, you part with 1 / 5 * 15 = 3 apples. The total number of apples remaining is 15 - 3 = 12 apples. The answer is 12.
Question: At its current growth rate, a certain plant will be 80 feet tall after a year. If the plant grows at the same rate every month and is currently 20 feet tall, what's its monthly growth rate in feet?
Answer: If the plant is currently 20 feet tall, it will have grown by 80 - 20 = 60 feet after a year. Since a year has 12 months, and the tree grows at the same rate every month, the tree grows at 60 / 12 = 5 feet every month. The answer is 5.
[Question]Thomas owns 200 books. He decides to sell them and use the money to buy records. Each book sells for $1.5. A record costs $3. If he buys 75 records, how much money does he have left over?
[Answer]He makes $300 selling the books because 200 x 1.5 = 300. He spends $225 on records because 75 x 3 = 225. He has $75 left because 300 - 225 = 75. The answer is 75.

Question: It is the rainy season in central Texas. It rained for 7 hours on Monday at a rate of 1 inch per hour. On Tuesday, it rained for 4 hours at a rate of 2 inches per hour, and on Wednesday, it rained for 2 hours at a rate of twice that of the previous day. What is the total combined rainfall, in inches, for these three days?
Answer: On Monday, 7 hours of rain at a rate of 1 inch per hour is 7 * 1 = 7 inches of rain. On Tuesday, 4 hours of rain at a rate of 2 inches per hour is 4 * 2 = 8 inches of rain. Twice the rate of Tuesday is 2 * 2 = 4 inches per hour. Wednesday, 2 hours of rain at a rate of 4 inches per hour is 2 * 4 = 8 inches of rain. The combined total of the rainfall for these three days is 7 + 8 + 8 = 23 inches of rain. The answer is 23.
Q: Clayton plays basketball on a team. He has played three games so far. In the first game, he scored 10 points. In the second game, he scored 14 points. In the third game, he scored 6 points. In the fourth game, he scored the average of his points from the first three games. How many total points did Clayton score during the first four games?
