Q: Josh had 100 gummy bear candies. He decided to give his 3 siblings 10 candies each. Then he gave half of the remaining candies to his best friend. If he only wants to eat 16 gummy bear candies, how many candies are left to be shared with others?
A: Josh gave a total of 3 x 10 = 30 candies to his siblings. He was then left with 100 - 30 = 70 candies. He gave 70 / 2 = 35 candies to his best friend. So he had 70 - 35 = 35 candies left. Since he only wants to eat 16 candies, there are still 35 - 16 = 19 candies left to be shared with others. The answer is 19.
Question: Vincent has 72 inches of rope that he wants to use for a project, but he needs to cut it into smaller pieces first. He cuts it into 12 equal length pieces, but then he realizes it's too short, so he ties three pieces together. The knots then make each piece 1 inch shorter. How long are his pieces of rope after all this?
Answer: Each small piece is 6 inches because 72 / 12 = 6. Each piece is then 5 inches long after the knots are tied because 6 - 1 = 5. The three pieces tied together are now 15 inches long because 5 x 3 = 15. The answer is 15.
[Question]A box is 8 inches in height, 10 inches in width, and 12 inches in length. A wooden building block is 3 inches in height, 2 inches in width, and 4 inches in length. How many building blocks can fit into the box?
[Answer]The volume of the box is 8 x 10 x 12 = 960 cu in. The volume of a wooden block is 3 x 2 x 4 = 24 cu in. 960 / 24 = 40 wooden blocks can fit into the box. The answer is 40.
Q: Janice can type 6 sentences per minute. Today at work, Janice continued working on a paper she started typing yesterday. She typed for 20 minutes, took a break, and typed 15 minutes longer. She then had to erase 40 sentences she had typed incorrectly. After a meeting, she typed for 18 minutes more. In all, the paper had 536 sentences by the end of today. How many sentences did she start with today?
A: Janice had X sentences from yesterday already typed to start with today. Janice typed 6 * 20 = 120 sentences before her break. She typed 6 * 15 = 90 sentences after her break. She typed 6 * 18 = 108 sentences after her meeting. Therefore, she typed 120 + 90 + 108 = 318 sentences today in all. She had to erase 40 sentences, so she had 318 - 40 = 278 sentences that she typed today left. The paper had X + 278 = 536 sentences at the end of today. Thus, she had X = 536 - 278 = 258 sentences typed on the paper to start with today. The answer is 258.
