[Question]Eugene built a model house out of toothpicks and a deck of playing cards. For every card, he used 75 toothpicks. The deck of playing cards had 52 cards, and Eugene used all but 16 of the cards to build his house. If a box of toothpicks contains 450 toothpicks, how many boxes of toothpicks did Eugene use to create his model house?
[Answer]If Eugene used all but 16 of the 52 cards, then he used 52 - 16 = 36 cards. If for every card he used 75 toothpicks, then a box of toothpicks would have enough toothpicks for 450 / 75 = 6 cards. Since one box has enough toothpicks for 6 cards, then for 36 cards he would need 36 / 6 = 6 boxes of toothpicks. The answer is 6.
Q: Rajesh walked 10 kilometers less than 4 times the distance that Hiro walked. Together they walked 25 kilometers. How many kilometers did Rajesh walk?
A: Let H = distance Hiro walked. 4H - 10 = distance Rajesh walked. H + 4H - 10 = 25. 5H - 10 = 25. 5H = 35. Hiro walked 7 km so Rajesh walked 4(7) - 10 = 18 km. Rajesh walked 18 kilometers. The answer is 18.
Question: A town is trying to clear litter from its streets. The council pays for adding 14 trash cans to the streets and also pays for adding twice as many trash cans to the back of stores. How many trash cans has the town paid for?
Answer: At the back of stores, the town has paid for 14 trash cans on the streets * 2 = 28 trash cans. The town has therefore added 14 trash cans on the streets + 28 trash cans at the back of stores = 42 trash cans. The answer is 42.
[Question]3 people run for president. John manages to capture 150 votes. James captures 70% of the remaining vote. If there were 1150 people voting, how many more votes did the third guy get than John?
[Answer]There were 1150 - 150 = 1000 people who didn't vote for John. That means James got 1000 * .7 = 700 votes. So the other candidate got 1000 - 700 = 300 votes. This means he got 300 - 150 = 150 more votes than John. The answer is 150.
[Question]A hardware store sold 10 graphics cards, 14 hard drives, 8 CPUs, and 4 pairs of RAM in one week. The graphics cards cost $600 each, hard drives cost $80 each, CPUs cost $200 each, and RAM cost $60 for each pair. How much money did the store earn this week?
[Answer]
It earned 10 * 600 = 6000 dollars by selling graphics cards. It earned 14 * 80 = 1120 dollars by selling hard drives. It earned 8 * 200 = 1600 dollars by selling CPUs. It earned 4 * 60 = 240 dollars by selling RAM. Overall it earned 6000 + 1120 + 1600 + 240 = 8960 dollars this week. The answer is 8960.
