Q: Sally took 342 pens to her class of 44 students. If she gave 7 pens to each student, left half of the remainder in her locker, and took the rest home, how many did she take home?
A: She gave 7 pens each to 44 students for a total of 7 * 44 = 308 pens. There are now 342 - 308 = 34 pens left. She left half of 34 pens in her locker which is 34 * (1 / 2) = 17 pens. She took 34 - 17 = 17 pens home. The answer is 17.

Q: There are 2000 pinecones on the ground. 20% are eaten by reindeer. Twice as many are eaten by squirrels as reindeer. 25% of the remainder are collected to make fires. How many pinecones are left?
A: First find the number of pinecones eaten by reindeer: 20% * 2000 pinecones = 400 pine cones. Then find the total number of pinecones eaten by squirrels: 400 pine cones * 2 = 800 pine cones. Then subtract those two amounts to find the number of pinecones left: 2000 pinecones - 400 pine cones - 800 pine cones = 800 pinecones. Divide that number by 4 to find the number that are collected for fires: 800 pinecones / 4 = 200 pine cones. Then subtract that number from the 800 pinecones to find the total left on the ground: 800 pine cones - 200 pinecones = 600 pine cones. The answer is 600.

Q: The chocolate factory produces 50 candies per hour. It has to fulfill an order and produce 4000 candies. How many days will it take to complete the order if the factory works for 10 hours every day?
A:
It will take 4000 candies / 50 candies / hour = 80 hours to make all the candy. It will take 80 hours / 10 hours / day = 8 days to complete the order. The answer is 8.
