[Question]Itzayana is 4 inches taller than Zora, who is 8 inches shorter than Brixton. If Zara is 64 inches tall and has the same height as Brixton, calculate the average height of the four people.
[Answer]Since Brixton has the same height as Zara which is 64 inches, Zora, who is 8 inches shorter than Brixton, is 64 - 8 = 56 inches tall. Zara and Brixton's height is 64 + 64 = 128 inches. If you add Zora's height, the three have a total height of 128 + 56 = 184. Itzayana is 4 inches taller than Zoran which means she is 56 + 4 = 60 inches tall. The total height of the four friends is 60 + 184 = 244. The average height of the three is 244 / 4 = 61. The answer is 61.
Q: Nina wants to give presents to her children. She buys three toys at $10 each, two packs of basketball cards at $5 each, and five shirts at $6 each. How much does she spend in all?
A: Three toys cost 3 x $10 = $30. Two packs of basketball cards cost 2 x $5 = $10. And, five shirts cost 5 x $6 = $30. Therefore, Nina spends a total of $30 + $10 + $30 = $70 in all. The answer is 70.
Question: John drinks 2 energy drinks. 1 of them is a 12-ounce drink with 250 grams of caffeine. The second drink is 3 times more caffeinated per ounce but only 2 ounces. He then takes a caffeine pill that has as much caffeine as his 2 drinks combined. How much caffeine did he consume?
Answer: The second drink was 2 / 12 = 1 / 6 the size of the first drink. So it had 1 / 6 * 3 = 1 / 2 the caffeine. That means it had 1 / 2 * 250 = 125 grams of caffeine. So the total amount of caffeine he drank was 125 + 250 = 375 grams. So he consumed 375 * 2 = 750 grams of caffeine for the day. The answer is 750.
[Question]Karen’s work tote bag is twice the weight of her husband Kevin’s briefcase when the briefcase is empty. When Kevin puts his laptop and work papers in his briefcase, it is twice the weight of Karen’s tote. Kevin’s work papers are a sixth of the weight of the contents of his full briefcase. If Karen’s tote weighs 8 pounds, how many more pounds does Kevin’s laptop weigh than Karen’s tote?
[Answer]Kevin’s full briefcase is 2 * 8 = 16 pounds. His empty briefcase is 8 / 2 = 4 pounds. The contents of his briefcase weigh 16 - 4 = 12 pounds. His work papers weigh 12 / 6 = 2 pounds. Thus, his laptop weighs 12 - 2 = 10 pounds. Therefore, Kevin’s laptop weighs 10 - 8 = 2 pounds more than Karen’s tote. The answer is 2.
Q: There is very little car traffic on Happy Street. During the week, most cars pass it on Tuesday - 25. On Monday, 20% less than on Tuesday, and on Wednesday, 2 more cars than on Monday. On Thursday and Friday, it is about 10 cars each day. On the weekend, traffic drops to 5 cars per day. How many cars travel down Happy Street from Monday through Sunday?
A: On Monday there are 20 / 100 * 25 = 5 cars passing the street less than on Tuesday. So on Monday, there are 25 - 5 = 20 cars on Happy Street. On Wednesday, there are 20 + 2 = 22 cars on this street. On Thursday and Friday, there is a total of 10 * 2 = 20 cars passing. On the weekend 5 * 2 = 10 cars are passing. So from Monday through Sunday, there are 20 + 25 + 22 + 20 + 10 = 97 cars traveling down the street. The answer is 97.
