Q: There are twenty-two people in a waiting room. If three more people arrive, the number of people in the waiting room becomes five times the number of people inside the interview room. How many people are in the interview room?
A: There are twenty - two people in a waiting room, and if three more people arrive, the number increases to 22 + 3 = 25. If three more people arrive, the number of people in the waiting room becomes five times the number of people that are inside the interview room, meaning there are 25 / 5 = 5 people inside the interview room. The answer is 5.
Question: Karen is paddling her canoe up a river against the current. On a still pond, Karen can paddle 10 miles per hour. The river flows in the opposite direction at 4 miles per hour. If the river is 12 miles long, how many hours will it take Karen to paddle up it?
Answer: First find Karen's net speed by subtracting the speed of the current: 10 mph - 4 mph = 6 mph. Then divide the length of the river by Karen's speed to find how long it takes her to paddle up it: 12 miles / 6 mph = 2 hours. The answer is 2.
[Question]Bob is building raised beds for his vegetable garden. Each bed is 2 feet high, 2 feet wide, and 8 feet long. The sides are going to be built of 1-foot wide planks. If Bob buys his lumber in 8-foot-long boards, planning to cut some of them for the shorter lengths he'll need, how many 8-foot long planks will he need to construct 10 raised beds?
[Answer]Each raised bed is 8 feet long, the same as the planks, so the long sides of the beds will each be 1 plank long. Each raised bed is 2 feet wide, or 2 / 8 = 1 / 4 the length of the planks, so the short sides will each be 1 / 4 plank long. Each bed is 2 feet tall, and the planks are 1 foot wide, so each side will need 2 pieces of lumber of the same length. So each bed will require 2 * 2 * 1.25 = 4 * 1.25 = 5 planks of wood. Bob wants to build 10 raised beds, so he will need 10 * 5 = 50 planks of lumber. The answer is 50.
Q: At a CD store, 40% of the CDs cost $10 each, and the rest cost $5 each. Prince bought half the CDs sold at $10 each, and all of the CDs sold at $5 each. If the total number of CDs was 200, how much money did Prince spend on buying the CDs?
A: The number of CDs selling at $10 each at the store is 40 / 100 * 200 = 80. This means the store sells 200 - 80 = 120 CDs at $5 each. Prince bought 1 / 2 * 80 = 40 of the CDs selling at $10 each. The total amount of money Prince paid for the 40 CDs selling at $10 each is $40 * 10 = $400. If he bought all the CDs selling at $5 each, he paid a total of $5 * 120 = $600. For all the CDs he bought, Prince spent $600 + $400 = $1000. The answer is 1000.
Question: Mike is building a bridge out of LEGO blocks. To be successful he needs at least 40 bricks of type A, and half that many of type B. In total, he needs to use 150 bricks. How many bricks of other types than mentioned is he going to use?
Answer:
Mike is using 40 blocks / 2 = 20 blocks of type B. He uses in total 40 blocks + 20 blocks = 60 blocks of type A and B. So he is going to use 150 blocks - 60 blocks = 90 blocks of other types. The answer is 90.
