Question: Berry wants to make sure he reads an average of 50 pages a day. This week he read 43 pages on Sunday, 65 pages on Monday, and 28 pages on Tuesday. He had a soccer game and fell asleep early on Wednesday so he read nothing. On Thursday he read 70 pages, and on Friday he read 56 pages. How many pages does he have to read on Saturday to reach his goal?
Answer: He has to read 350 pages a week because 7 x 50 = 350. He has read 262 pages because 43 + 65 + 28 + 70 + 56 = 262. He has to read 88 pages on Saturday because 350 - 262 = 88. The answer is 88.

Question: Tom Sawyer has tricked his friends into whitewashing Aunt Polly's 100-foot fence. His first friend, Ben, whitewashed 10 feet. His second friend Billy whitewashed a fifth of the remaining fence. A third friend, Johnny, whitewashed a third of the fence that was left after that. How much of the fence still needs to be whitewashed?
Answer: It's a 100 - foot fence, and Ben whitewashed 10 feet, so there are 100 - 10 = 90 feet left after Ben is done. Billy whitewashed a fifth of that, or 90 / 5 = 18 feet. There is now 90 - 18 = 72 feet of fence left. Johnny whitewashes a third of that, or 72 / 3 = 24 feet. That leaves 72 - 24 = 48 feet of fence left to be whitewashed. The answer is 48.

Question: Keiko sent 111 text messages last week. This week she sent 50 less than double what she sent last week. How many text messages did Keiko send last week and this week combined?
Answer: Last week = 111 texts. This week = (2 * 111) - 50 = 172 texts. 111 + 172 = 283 texts. Keiko sent 283 texts last week and this week combined. The answer is 283.

Question: Karen and Donald and their 6 children are sharing a beach house with Tom and Eva and their 4 children. If there are 16 legs in the pool, how many people are not in the pool?
Answer:
Karen and Donald and their 6 children are a party of 1 + 1 + 6 = 8 people. Tom and Evan and their 4 children are a party of 1 + 1 + 4 = 6 people. All total, there are 8 + 6 = 14 people at the beach house. There are 16 legs in the pool and everyone has 2 legs so there are 16 / 2 = 8 people in the pool. There are 14 people total at the beach house and 8 people are in the pool so 14 - 8 = 6 people are not in the pool. The answer is 6.
