[Question]It takes 50 minutes to cut a woman's hair, 15 minutes to cut a man's hair, and 25 minutes to cut a kid's hair. If Joe cut 3 women's, 2 men's, and 3 children's hair, how much time did he spend cutting hair?
[Answer]He spent 3 * 50 = 150 minutes cutting women's hair. He spent 2 * 15 = 30 minutes cutting men's hair. He spent 3 * 25 = 75 minutes cutting children's hair. He spent a total of 150 + 30 + 75 = 255 minutes. The answer is 255.
Q: Tedra is harvesting his tomatoes. He harvests 400 kg on Wednesday, and half as much on Thursday. He harvests a total of 2000 kg on Wednesday, Thursday, and Friday. How many tomatoes of the number he harvested on Friday are remaining if he gives away 700kg of them to his friends?
A: Tedra harvests 1 / 2 * 400 kg = 200 kg of tomatoes on Thursday. Tedra harvests 2000 kg - 400 kg - 200 kg = 1400 kg of tomatoes on Friday. After giving away tomatoes to his friends, he is left with 1400 kg - 700 kg = 700 kg of tomatoes. The answer is 700.
Question: Axel bought an aquarium that was marked down 50% from an original price of $120. But he also paid additional sales tax equal to 5% of the reduced price. What was the total cost of the aquarium?
Answer: The aquarium was bought for $120 x 50 / 100 = $60 less. So the marked down price of the aquarium was $120 - $60 = $60. Axel paid $60 x 5 / 100 = $3 additional for the sales tax. Therefore, the total cost of the aquarium was $60 + $3 = $63. The answer is 63.
[Question]Michelangelo has 28 ceilings to paint. This week, he paints 12 of them. Next week, he will paint 1/4 the number of ceilings he did this week. How many ceilings will be left to paint after next week?
[Answer]After this week, Michelangelo will have 28 - 12 = 16 more ceilings to paint. Next week, Michelangelo will paint 12 / 4 = 3 ceilings. Michelangelo will have 16 - 3 = 13 more ceilings to paint. The answer is 13.
Q: Billy can spit a watermelon seed 30 inches. Madison can spit a watermelon seed 20% farther than Billy. Ryan can spit a watermelon seed 50% shorter than Madison. How far can Ryan spit a watermelon seed?
A: Madison can spit a seed 20% farther than Billy's 30 inches so that's .20 * 30 = 6 inches farther. Billy spits a seed 30 inches and Madison can spit 6 inches farther for a total of 30 + 6 = 36 inches. Ryan can spit a seed 50% shorter than Madison's 36 inches for a total of .50 * 36 = 18 inches. The answer is 18.

Andrew is having 4 friends over who will get 3 donuts each, 4 x 3 = 12 donuts total. Andrew’s mother wants to get 1 extra donut for each of Andrew’s friends, 3 donuts + 1 extra = 4 donuts for each of Andrew's friends. Andrew’s mother is buying 12 + 4 extra donuts for Andrew’s friends = 16 total donuts. Andrew’s mother is also going to get 3 + 1 extra donut for Andrew = 4 donuts. Andrew’s mother will need to buy 16 donuts for Andrew’s friends + 4 donuts for Andrew = 20 total donuts. The answer is 20.
