Question: Michael has a chicken farm. His chickens increase in number by 150 chickens annually. If the number of chickens on his farm now is 550, how many will he have after 9 years?
Answer: The number of the increase in chicken after 9 years is 150 * 9 = 1350. So the total number of the chicken in Michael's farm will be 550 + 1350 = 1900. The answer is 1900.
[Question]Aaron is gathering can lids to take to the recycling center. He uses 3 equal-sized boxes of canned tomatoes and adds the lids he gets to the 14 can lids he already has. He is now taking 53 can lids to the recycling center. How many cans lids did he get from each box?
[Answer]Calculating the difference between the can lids Aaron has now and the amount that he had initially shows there were 53 – 14 = 39 can lids in the boxes of canned tomatoes. As the boxes are the same size, splitting these can lids equally shows that there were 39 / 3 = 13 can lids in each box. The answer is 13.
Q: Michael saved 5 of his cookies to give Sarah, who saved a third of her 9 cupcakes to give to Michael. How many desserts does Sarah end up with?
A: Sarah saved 1 / 3 of her 9 cupcakes to give Michael, so she has 2 / 3 x 9 = 6 cupcakes left. Michael saves 5 of his cookies for Sarah, which she adds to her 6 cupcakes. Sarah has 5 + 6 = 11 desserts. The answer is 11.
Question: Lilly and Fiona are cleaning a room. Between them, it takes 8 hours to clean the room. A quarter of the time spent cleaning was by Lilly and Fiona was responsible for the rest of the cleaning. How long, in minutes, was Fiona cleaning?
Answer: Lilly cleaned for 8 hours / 4 = 2 hours. This means that Fiona was cleaning for 8 hours total cleaning – 2 hours Lilly’s cleaning = 6 hours. So in minutes, Fiona was cleaning for 6 hours * 60 minutes in an hour = 360 minutes. The answer is 360.
[Question]Three times the sum of marbles that Atticus, Jensen, and Cruz have is equal to 60. If Atticus has half as many marbles as Jensen, and Atticus has 4 marbles, how many marbles does Cruz have?
[Answer]Three times the sum of marbles that Atticus, Jensen, and Cruz have is equal to 60, meaning together they have 60 / 3 = 20 marbles. If Atticus has half as many marbles as Jensen, and Atticus has four marbles, Jensen has 2 * 4 = 8 marbles. Together, Atticus and Jensen have 8 + 4 = 12 marbles. Since the sum of marbles that Atticus, Jensen, and Cruz have is equal to 20, and Atticus and Jensen have 12 marbles, Cruz has 20 - 12 = 8 marbles. The answer is 8.
[Question]Mike has to get an x-ray and an MRI. The x-ray is $250 and the MRI is triple that cost. Insurance covers 80%. How much did he pay?

The MRI cost 250 * 3 = $750. So between the two things he pays 250 + 750 = $1000. Insurance covered 1000 * .8 = $800. So he had to pay 1000 - 800 = $200. The answer is 200.
