Question: A housewife goes to the market. She spent 2/3 of her $150. How much does she have left?
Answer: The housewife has 3 / 3 - 2 / 3 = 1 / 3 of $150 left. This means she has $150 * (1 / 3) = $50 left. The answer is 50.
[Question]Karen is constantly trying to stop the raccoons from getting in her trash. The first lock she tries stalls them for 5 minutes. The next lock stalls them for 3 minutes less than three times as long as the first lock. When Karen tries both locks at once, it stalled the raccoons for five times as long as the second lock alone. How long is that?
[Answer]First find how long the second lock stalls them: 5 minutes * 3 - 3 minutes = 12 minutes. Then multiply that amount by 5 to find the total time the third lock stall the raccoon: 12 minutes * 5 = 60 minutes. The answer is 60.
Q: Claire is scheduling her day. She has four hours to clean and two hours to cook, then divides the rest of her working day equally between crafting and tailoring. She then sleeps eight hours. If all of this takes place within one day, how many hours did Claire spend crafting?
A: We know Claire has spent a total of 24 hours in a day - 4 hours cleaning - 2 hours cooking - 8 hours sleeping = 10 hours crafting and tailoring. Since she split her time equally, she must have spent 10 hours * 0.5 = 5 hours crafting. The answer is 5.
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.
[Question]Gary is buying chlorine for his rectangular pool, which is 10 feet long, 8 feet wide, and 6 feet deep. Gary needs to buy one quart of chlorine for every 120 cubic feet of water in his pool. If chlorine costs $3 a quart, how much does Gary spend on chlorine?
[Answer]First find the volume of the pool by multiplying the length by the width by the height: 10 ft * 8 ft * 6 ft = 480 cubic feet. Then divide the volume of the pool by the number of cubic feet one quart of chlorine can sterilize: 480 cubic feet / 120 cubic feet / quart = 4 quarts. Then multiply the number of quarts Gary needs to buy by the price per quart to find out how much money he spends: $3 / quart * 4 quarts = $12. The answer is 12.
[Question]Roe saved $10 per month from January to July and saved $15 per month from August to November. How much should she save in December so she will have a total savings of $150 in the year?
[Answer]
Since there are 7 months from January to July, then Roe's savings for those months sum up to $10 x 7 = $70. Since there are 4 months from August to November, then her savings for those months sum up to $15 x 4 = $60. Her total savings from January to November is $70 + $60 = $130. Therefore, she needs to save $150 - $130 = $20 in December. The answer is 20.
