Question: Jamal bought 4 half dozen colored crayons at $2 per crayon. What was the total cost of the crayons that she bought?
Answer: Since a dozen has 12 items, a half dozen has 1 / 2 * 12 = 6 items. Since Jamal bought four half dozen colored crayons, he bought 4 * 6 = 24 colored crayons. If each crayon's cost was $2, Jamal paid $2 * 24 = $48 for all the crayons he bought. The answer is 48.
[Question]Tyson can swim at a speed of 3 miles per hour in a lake and 2.5 mph in an ocean. This season, half his races happened in lakes and half his races happened in the ocean. He had ten total races, each of which was 3 miles long. How much time did he spend in his races?
[Answer]He did 5 races in the lake because 10 / 2 = 5. He did 5 races in the ocean because 10 / 2 = 5. He raced 15 miles in the lake because 5 x 3 = 15. His lake races took 6 hours because 15 / 2.5 = 6. He raced 15 miles in the ocean because 5 x 3 = 15. His ocean races took 5 hours because 15 / 3 = 5. He spent 11 hours racing because 5 + 6 = 11. The answer is 11.

Question: Mary had 6 lambs and 2 of the lambs had 2 babies each. She traded 3 lambs for one goat. One morning, she woke up and found an extra 7 lambs in the field. How many lambs does Mary have?
Answer: 2 of her lambs had 2 babies each so that adds 2 * 2 = 4 lambs. She starts with 6 and adds 4 baby lambs so she had 6 + 4 = 10 lambs. She traded 3 of those lambs for a goat so she has 10 - 3 = 7 lambs. She has 7 and woke up to find 7 more lambs in the field so she has a total of 7 + 7 = 14 lambs. The answer is 14.
