[Question]Angela wants to check her math homework answers with her friends, but some of them aren't done yet. Out of 20 problems, Martha has finished 2, Jenna has finished four times the number Martha did minus 2, and Mark has finished half the number Jenna did. If none of the friends worked on any of the same problems, how many problems have no one but Angela finished?
[Answer]Four times the number of problems Martha answered is 4 x 2 = 8. So, Jenna answered 8 - 2 = 6 problems. The number of problems Mark answered is 6 / 2 = 3. The total number of problems Martha, Jenna, and Mark answered is 2 + 6 + 3 = 11. So, this means Angela was able to answer 20 - 11 = 9 problems. The answer is 9.
Q: In the second hour of a storm it rains 7 inches more than twice the amount it rained the first hour. The total amount of rain in the first two hours is 22 inches. How much did it rain in the first hour?
A: Let x be the amount of rain in the first hour. It rained 2x + 7 inches in the second hour. x + 2x + 7 = 22. 3x + 7 = 22. 3x = 15. x = 5 inches. The answer is 5.
Question: The distance between Arizona and New York is around 2,000 miles by plane. The distance between the 2 different US states increases by 40% if someone decides to drive instead of flying. Missouri is midway between Arizona and New York. How far away is Missouri from New York if someone decides to go by car?
Answer: The distance between Arizona and New York is 2,000 miles by plane. The distance between Arizona and New York is 40% greater by car, which is 40% * 2,000 = 800 miles. This results in a total of 2,000 + 800 = 2,800 miles between Arizona and New York by car. If Missouri is in the middle of the way between Arizona and New York, someone would drive half of the distance to go from Missouri to New York, which is 2,800 / 2 = 1,400. The answer is 1400.
[Question]At the Boisjoli farm, there is a chicken coop where 270 hens and 3 roosters live. Every morning, around 8 a.m., Ms. Mosel goes to collect the eggs because, every morning, each hen lays one.
