[Question]Ann, Bill, Cate, and Dale each buy personal pan pizzas cut into 4 pieces. If Bill and Dale eat 50% of their pizzas and Ann and Cate eat 75% of the pizzas, how many pizza pieces are left uneaten?
[Answer]In total, there are 4 x 4 = 16 pizza pieces. Bill and Dale eat 2 x 4 x 50% = 4 pieces. Ann and Cate eat 2 x 4 x 75% = 6 pieces. The four of them eat 4 + 6 = 10 pieces. There are 16 - 10 = 6 pizza pieces uneaten. The answer is 6.
Q: A tractor trailer has a load of 50000 pounds. 10% of the weight gets unloaded at the first store, and 20% of the remaining load is removed at the second store. How much weight, in pounds, is left on the truck after the two deliveries?
A: First Store:50000(.10) = 5000. 50000 - 5000 = 45000 pounds. Second Store:45000(.20) = 9000. 45000 - 9000 = 36000 pounds. The answer is 36000.
Question: Kenny wants to make sure he does more jumping jacks every week than he did the week before. He recorded that last week he did 324 total jumping jacks. On Saturday of this week, he looks at his records and sees that on Sunday he did 34. On Monday he did 20. On Tuesday he skipped a day. On Wednesday he did 123. On Thursday he did 64. On Friday he did 23. How many does he have to do on Saturday to make sure he beats last week's number?
Answer: He has already done 264 this week because 34 + 20 + 123 + 64 + 23 = 264. If he does 60 he will have done as many as last week because 324 - 264 = 60. He has to do 61 on Saturday because 60 + 1 = 61. The answer is 61.
[Question]On a 16 GB (gigabyte) capacity USB drive, 50% is already busy. Calculate the number of gigabytes still available.
[Answer]We calculate 50% of 16 GB:. 50 / 100 * 16 GB = 0.5 * 16 GB = 8 GB. That leaves 16 GB - 8 GB = 8 GB available on this key. The answer is 8.
Q: Tom decides to renovate a house. There are 3 bedrooms and each bedroom takes 4 hours to renovate. The kitchen takes 50% longer than each bedroom. The living room took twice as much time as everything else combined. How long did everything take?
A: The kitchen took 4 * .5 = 2 hours longer than the bedrooms. So the kitchen took 4 + 2 = 6 hours. The bedrooms took 3 * 4 = 12 hours. So the kitchen and bedrooms combined took 12 + 6 = 18 hours. The living room took 18 * 2 = 36 hours. So everything took a total of 18 + 36 = 54 hours. The answer is 54.
