Question: To try to get the class to eat more vegetables, the teacher says that she will start giving them good character points that the class can redeem for a movie day if they earn enough. The students need to earn 200 points to win the movie day. Each time a student eats their vegetables at lunch she gives the student 2 points. There are 25 students in the class. If they have two school weeks, otherwise known as 10 days to win the movie, what is the average number of vegetables each student must eat per school week to get a movie day?
Answer: The students need eat 100 vegetables in total because 200 / 2 = 100. Each student needs to eat on average 4 vegetables because 100 / 25 = 4. Each student needs to eat 2 vegetables per school week because 4 / 2 = 2. The answer is 2.

Question: Last month, a factory made 12000 dolls and their associated accessories. The accessories for each doll included 2 shoes, 3 bags, 1 set of cosmetics, and 5 hats. If each doll took 45 seconds to make and each accessory took 10 seconds to make, what was the total combined machine operation time, in seconds, required to manufacture all of the dolls and their accessories?
Answer: The number of shoes the factory made was 12000 dolls x 2 shoes / doll = 24000 shoes. The factory also made for each doll 12000 dolls x 3 bags / doll = 36000 bags. The set of cosmetics made for each doll was just one, so there are 12000 cosmetics sets. Finally, the number of hats for the dolls was 12000 dolls x 5 hats / doll = 60000 hats. In total, the number of accessories was 24000 + 36000 + 12000 + 60000 = 132000 accessories. The dolls took in total 12000 dolls x 45 seconds / doll = 540000 seconds to be made. All the accessories also took 132000 accessories x 10 seconds / accessory = 1320000 seconds. Combing both results, we have that the total time the machinery was working was 1320000 + 540000 = 1860000 seconds. The answer is 1860000.
[Question]Together 3 friends watched 411 short videos. Kelsey watched 43 more than Ekon. Ekon watched 17 less than Uma. How many videos did Kelsey watch?
[Answer]Let U = the number of videos Uma watched. Ekon = U - 17. Kelsey = (U - 17) + 43 = U + 26. U + U - 17 + U + 26 = 411. 3U + 9 = 411. 3U = 402. U = 134. Kelsey = 134 + 26 = 160 videos. Kelsey watched 160 videos. The answer is 160.
[Question]Cassidy is grounded for 14 days for lying about her report card, plus 3 extra days for each grade below a B. If Cassidy got four grades below a B, how long is she grounded for?
