[Question]: Keith and Blaine went fishing. Blaine caught 5 fish while Keith caught twice as many as Blaine's. How many fish did they catch together?
[Answer]: Keith caught 5 x 2 = 10 fish. Therefore, they caught a total of 5 + 10 = 15 fish.
So the answer is 15.

[Question]: James decides to cut down some trees. In the first 2 days, he cuts down 20 trees each day. For the next 3 days his 2 brothers help him cut down trees. They cut 20% fewer trees per day than James. How many total trees were cut down?
[Answer]: He cuts down 2 * 20 = 40 trees by himself. Each of his brothers cuts down 20 * .2 = 4 fewer trees per day. So they each cut down 20 - 4 = 16 trees. So for the next 3 days they cut down 20 + 16 * 2 = 52 trees per day. So they cut down 40 + 52 * 3 = 196 trees.
So the answer is 196.

[Question]: James needs 200 blueberries to make a pint of blueberry jam and then a quart of blueberry jam to make a blueberry pie. If there are two pints per quart, how many blueberries does James need to pick to make 6 pies?
[Answer]:
First find the total number of blueberries needed for one pie: 200 blueberries / pint * 2 pints / pie = 400 blueberries / pie. Then multiply that number by the number of pie to find the total number of blueberries James need: 400 blueberries / pie * 6 pies = 2400 blueberries.
So the answer is 2400.
