[Question]Kara has to drink 4 ounces of water every time she takes her medication. Her medication instructions are to take one tablet three times a day. She followed the instructions for one week, but in the second week, she forgot twice on one day. How many ounces of water did she drink with her medication over those two weeks?
[Answer]Kara drinks 4 * 3 = 12 ounces of water with her medication each day. In a week, she drinks 12 * 7 = 84 ounces of water with her medication. In two weeks, she drinks 84 * 2 = 168 ounces of water with her medication. One day, she forgot two tablets, so she did not drink 2 * 4 = 8 ounces of water. Thus, Kara drank 168 - 8 = 160 ounces of water with her medication over two weeks. The answer is 160.
Q: Randy had some money. Smith gave him another $200. Randy then gave Sally $1,200 and kept the rest. If Randy has $2000 left, how much money, in dollars, did Randy have at first?
A: After Smith gave him $200, Randy had 2000 + 1200 = 3200 dollars. Randy had 3200 - 200 = 3000 dollars at first. The answer is 3000.
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.
[Question]You walk twice as fast as Mr. Harris, and Mr. Harris took 2 hours to walk to the store. If your destination is 3 times further away than the store Mr. Harris walked to, how many hours will it take you to get there?
[Answer]First we find out how long it would take Mr. Harris to walk to your destination, which we find by multiplying his 2 hour walk by 3 since your destination is 3 times further away, meaning it would take him 2 * 3 = 6 hours. Since you walk twice as fast, it would take you half the time. Half of 6, 6 / 2 = 3 hours in total. The answer is 3.
Q: Bill has 6 times as many nuts as Harry, and Harry has twice as many nuts as Sue. If Sue has 48 nuts, how many do Bill and Harry have combined?
A: If Sue has 48 nuts, and Harry has twice as many nuts as Sue, Harry has 2 * 48 = 96 nuts. Bill has 6 times as many nuts as Harry, and since Harry has 96 nuts, Bill has 96 * 6 = 576 nuts. Combined, Bill and Harry have 576 + 96 = 672 nuts. The answer is 672.
Question: Carson runs a carpool for five of his friends. The five of them cover all the gas expenses to compensate Carson for his time. Their total commute is 21 miles one way, gas costs $2.50/gallon, Carson's car gets 30 miles/gallon, and they commute to work 5 days a week, 4 weeks a month. How much does each person pay toward gas monthly?

First find the total number of monthly commutes: 5 days / week * 4 weeks / month = 20 days / month. Then multiply the distance of the commute one way by the two ways: 21 miles * 2 = 42 miles. Then multiply the number of commutes by the number of miles per commute: 42 miles / commute * 20 commutes = 840 miles. Then divide the number of miles by the car's gas mileage: 840 miles / 30 miles / gallon = 28 gallons. Then multiply that number by the cost of each gallon to find the total cost: 28 gallons * $2.50 / gallon = $70. Then divide the total cost by the number of friends to find the cost per person: $70 / 5 people = $14 / person. The answer is 14.
