[Question]Faye had $20. Today, her mother gave her twice as much as her money. If she bought ten cupcakes at $1.50 each and five boxes of cookies at $3 per box, how much money did she have left?
[Answer]Faye's mother gave her 2 x $20 = $40. So, Faye had a total of $20 + $40 = $60. Ten cupcakes cost 10 x $1.50 = $15. Five boxes of cookies cost 5 x $3 = $15. Thus, Faye spent $15 + $15 = $30. Therefore, Faye has $60 - $30 = $30 left. The answer is 30.

[Question]Nikka has a 100 stamp collection. Thirty-five percent of her stamps are Chinese, 20% are US stamps, and the rest are Japanese stamps. How many Japanese stamps does Nikka have?
[Answer]Nikka has 100 x 35 / 100 = 35 Chinese stamps. She has 100 x 20 / 100 = 20 US stamps. So, Nikka has 35 + 20 = 55 stamps that are not Japanese. Thus, Nikka has 100 - 55 = 45 Japanese stamps. The answer is 45.

[Question]A pumpkin patch allows people to come pick pumpkins to carve in the fall every year. They charge $3 per person for a pumpkin. The remaining pumpkins get turned into cans of pie filling, 3 pumpkins to a can. They grew 83 pumpkins this year and made $96 selling pumpkins for carving. How many cans of pie filling will the pumpkin patch produce?
[Answer]The pumpkin patch sold 96 / 3 = 32 pumpkins. They have 83 - 32 = 51 pumpkins left. Thus, the pumpkin patch will produce 51 / 3 = 17 cans of pie filling. The answer is 17.

[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.
