Question: Scott runs 3 miles every Monday through Wednesday. Then he runs twice as far he ran on Monday every Thursday and Friday. How many miles will he run in a month with 4 weeks?
Answer: Scott runs 3 x 2 = 6 miles every Thursday and Friday. The total miles run by Scott for a week from Monday through Wednesday is 3 x 3 = 9 miles. The total miles run by Scott for a week from Thursday to Friday is 6 x 2 = 12 miles. So, in a week, Scott runs a total of 9 + 12 = 21 miles. Thus, he runs a total of 21 x 4 = 84 miles in a month. The answer is 84.
[Question]Kelly booked a three week vacation to visit relatives. The first day, she spent traveling. The next 5 days she spent at her Grandparents' house. The next day, she spent traveling. Then, she spends the next 5 days at her brother's house. Then she spent two days traveling to her sister's house, spent several days at her sister's house, and then spent two more days traveling home. How many days did she spend at her sister's house?
[Answer]Three weeks is 7 * 3 = 21 days. She traveled one day to her grandparents' house, one day to her brother's house, two days to her sister's house, and two days back home for a total of 1 + 1 + 2 + 2 = 6 days. She spent 5 days at her grandparents' house and 5 days at her brother's house, for a total of 5 + 5 = 10 days. Thus, of the 21 vacation days, the number of days remaining to spend with her sister was 21 - 6 - 10 = 5 days. The answer is 5.
Q: Tim decides to get animals for his zoo. He buys 3 goats for $400 each. He gets twice as many llamas which cost 50% more each. How much did he spend?
A: The goats cost 3 * 400 = $1200. He buys 3 * 2 = 6 llamas. Each llama cost 400 * 1.5 = $600. So he spends 600 * 6 = $3600 on llamas. So the total cost was 1200 + 3600 = $4800. The answer is 4800.
Question: John decides to go back to school to get his PhD. He first takes 1 year of courses to get acclimated back to school life before starting his PhD. After that, he spends 2 years learning the basics of his field. He then starts research, and he spends 75% more time on research than he did learning the basics. He then spends half as long on writing his dissertation as his acclimation period. How long did it take him to do everything?
Answer: It took him 2 * .75 = 1.5 years longer to do his research than it took to learn the basics. So it took him a total of 2 + 1.5 = 3.5 years to do research. His dissertation took 1 / 2 = .5 years to write. So everything together took 1 + 2 + 3.5 + .5 = 7 years. The answer is 7.
[Question]Marcia needs to add 3 skirts, 2 pairs of pants and 5 blouses to her work wardrobe. A department store is offering a sale on pants; buy 1 pair get 1 pair 1/2 off. If her skirts are $20.00 each, the blouses are $15.00 and both pairs of pants are $30.00 each. How much will she spend on her wardrobe?
[Answer]The pants are $30.00 and are buy one get one 1 / 2 off so the second pair will be 30 * .5 = $15.00. The first pair of pants is $30.00 and the second pair is $15.00 so the pants cost 30 + 15 = $45.00. The skirts are $20.00 each and she’s buying 3 so that’s 20 * 3 = $60.00. The blouses are $15.00 each and she’s buying 5 so that’s 15 * 5 = $75.00. All total, her wardrobe will cost $45 for the pants, $60 for the skirts and $75 for the blouses so 45 + 60 + 75 = $180.00.
