[Question]Bobby can deadlift 300 pounds at 13. When he is 18 he can deadlift 100 pounds more than 250% of his previous deadlift. How many pounds did he add per year?
[Answer]His new deadlift is 300 * 2.5 + 100 = 850 pounds. So he added 850 - 300 = 550 pounds to his deadlift. This took 18 - 13 = 5 years. So he added 550 / 5 = 110 pounds per year. The answer is 110.
Q: A bottle of wine costs $20.00 today. When new tariffs are imposed in 2 months, the price of wine will increase by 25%. How much more expensive will 5 bottles of wine be in 2 months?
A: Today, 5 bottles of $20.00 wine will cost 5 * 20 = $100.00. In 2 months there will be a 25% tariff on the 5 bottles of wine that cost $100.00 so that makes the 5 bottles .25 * 100 = $25.00 more expensive. The answer is 25.

[Question]Jake trips over his dog 40% percent of mornings. 25% of the time he trips, he drops his coffee. What percentage of mornings does he NOT drop his coffee?
[Answer]First multiply the chance of each event happening to find the chance they both happen: 40% * 25% = 10%. Then subtract that percentage from 100% to find the percentage of the time Jake doesn't drop his coffee: 100% - 10% = 90%. The answer is 90.
Q: In preparation for the upcoming Olympics, Rita's swimming coach requires her to swim a total of 1,500 hours. Rita has already completed 50 hours of backstroke, 9 hours of breaststroke, and 121 hours of butterfly, but she is unhappy with her inconsistency. She has therefore decided to dedicate 220 hours every month practicing freestyle and sidestroke. How many months does Rita have to fulfill her coach’s requirements?
A: So far, time spent practicing backstroke, breaststroke, and butterfly is 50 + 9 + 121 = 180 hours. Since Rita’s must swim 1500 hours, the freestyle and sidestroke practice sessions will take 1500 - 180 = 1320 hours. Rita will practice for 220 hours / month, meaning she will meet her coach’s target in 1320 / 220 = 6 months. The answer is 6.
Question: A pen is longer than the rubber by 3 centimeters, and shorter than the pencil by 2 centimeters. Considering the pencil is 12 centimeters long, what is the total length of the rubber, the pen, and the pencil altogether?
Answer:
The pen is shorter than the pencil by 2 centimeters, so it's 12 - 2 = 10 centimeters long. That means the rubber is 10 - 3 = 7 centimeters long. So all accessories are 7 + 10 + 12 = 29 centimeters long altogether. The answer is 29.
