[Question]Jon decides to take up baseball. He can throw a fastball at 80 miles per hour.  He goes through intense training 4 times for 4 weeks each time and at the end of the last one he can throw a ball 20% faster. How much speed (in mph) did he gain per week, assuming he gained an equal amount of speed (in mph) each week?
[Answer]He threw the ball 80 * .2 = 16 mph faster. He was training for 4 * 4 = 16 weeks. So he gained 16 / 16 = 1 mph per week. The answer is 1.
Q: Mandy is 3 years old. Her brother is 4 times as old as she is. Her sister is 5 years younger than her brother. What is the age difference between Mandy and her sister?
A: Mandy's brother's age is 3 years x 4 = 12 years old. Her sister's age is 12 years - 5 years = 7 years old. The age difference between Mandy and her sister is 7 years - 3 years = 4 years. The answer is 4.
Question: Elon has 10 more teslas than Sam who has half the number of teslas as Chris. Chris has 6 teslas. How many teslas does Elon have?

Q: Mark wants to build a pyramid of soda cases that's four levels tall. Each level of the pyramid has a square base where each side is one case longer than the level above it. The top level is just one case. How many cases of soda does Mark need?
A: We know that the top level just has one case. Since each level has one more case per side than the level above it, the second level has sides that are 2 cases long. We can figure out how many cases we need for the second level by finding the area of a square with a side length of 2: 2 cases * 2 cases = 4 cases. The third level has three cases per side, so we need to find the area of a square with side length 3: 3 cases * 3 cases = 9 cases. The fourth level has a side length of 4, so we find its area with 4 cases * 4 cases = 16 cases. Finally, we add up the number of cases we need on each level: 1 cases + 4 cases + 9 cases + 16 cases = 30 cases. The answer is 30.
Question: A bottle can hold 2 cups of water. How many cups of water are needed to fill up 10 whole bottles and 5 half-capacity bottles?
Answer:
For 10 whole bottles, you will need 10 * 2 = 20 cups of water. With 5 half - capacity bottles, it requires 5 * 1 = 5 cups of water. In total, you need to have 25 + 5 = 30 cups of water to fill them all. The answer is 30.
