Question: Patrick has 4 hours less than twice the amount of time that Greg has left to finish his homework. Greg has six hours less than Jacob left to finish his homework. If Jacob has 18 hours left to finish his homework, calculate the total number of hours they all have left to finish their homework?
Answer: If Jacob has 18 hours left to finish his homework, Greg has 18 - 6 = 12 hours left to finish his homework. The total number of hours Jacob and Greg have left to finish their homework is 12 + 18 = 30 hours. Patrick has 4 hours less than twice Greg has left to finish his homework, meaning Patrick has 4 hours less than 12 * 2 = 24 hours left to finish his homework. Patrick has 24 - 4 = 20 hours left to finish his homework. Altogether, the three have 30 + 20 = 50 hours left to finish their homework. The answer is 50.
[Question]Michael makes birdhouses to sell at craft shows. He charges $22 for each large birdhouse, $16 for each medium birdhouse, and $7 for each small birdhouse. This week, he sold 2 large birdhouses, 2 medium birdhouses, and 3 small birdhouses. How much money, in dollars, did he make this week?
[Answer]Michael sold 2 large birdhouses for $22 each, so he made 2 * $22 = $44 from large birdhouse sales. Michael also sold 2 medium birdhouses for $16 each, so he made 2 * $16 = $32 from medium birdhouse sales. Michael sold 3 small birdhouses for $7 each, so he made 3 * 7 = $21 from small birdhouse sales. Since Michael made $44 from large birdhouse sales, $32 from medium birdhouse sales, and $21 for small birdhouse sales, he made $44 + $32 + $21 = $97 total this week. The answer is 97.
Q: Elmer has a pond that initially contained 2400 pollywogs, but these pollywogs matured into toads and left the pond at a constant rate of 50 pollywogs per day. In addition, Elmer has a son named Melvin, who loves to catch pollywogs, remove them from the pond, and release them into a nearby stream. For the first 20 days, Melvin caught 10 pollywogs per day and released them into the stream. How many days did it take for all of the pollywogs to disappear from the pond?
A: For the first 20 days, the combined rate of disappearance of pollywogs from the pond is 50 + 10 = 60 pollywogs per day. During these first 20 days, the total number of pollywogs removed was 60 * 20 = 1200 pollywogs. This means after 20 days there were 2400 - 1200 = 1200 pollywogs left in the pond. At a disappearance rate of rate 50 pollywogs per day, it will take an additional 1200 / 50 = 24 days for the rest of the pollywogs to disappear from the pond. Thus, overall, it will take 20 + 24 = 44 days for all of the pollywogs to disappear from the pond. The answer is 44.

[Question]Farrah ordered 4 boxes from Amazon containing 20 matchboxes each. If each matchbox has 300 sticks, calculate the total number of match sticks that Farah ordered?
[Answer]Farrah ordered 4 boxes from Amazon containing 20 matchboxes each, a total of 4 * 20 = 80 matchboxes. If each matchbox has 300 sticks, the total number of match sticks that Farah bought is 300 * 80 = 24000. The answer is 24000.
[Question]Brian likes to read books. He read one book that had 20 chapters, two books that had 15 chapters each, and one book that had half the chapters of the three previous books put together. How many chapters of books did Brian read?
[Answer]
Brian read two books with 15 chapters, so he read 2 * 15 = 30 chapters. He also read a book with 20 chapters, bringing the total for the first three to 30 + 20 = 50 chapters. He then read a book with half the chapters of his cumulative total so far, so it had 50 / 2 = 25 chapters. In total, he read 30 + 20 + 25 = 75 chapters. The answer is 75.
