Question: A farm has 5 less than 9 times the amount of hens as roosters. If there are 75 total chickens, how many hens are there?
Answer: Let x represent the number of roosters. Number of hens:9x - 5. Total:9x - 5 + x = 75. 10x - 5 = 75. 10x = 80. x = 8. Number of hens: 9(8) - 5 = 67. The answer is 67.

Q: 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?
A: 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.
Question: Edward the plumber is replacing a pipe in a bathroom wall. He needs to use 40 feet of copper pipe to complete the job. For every 5 feet of pipe, Edward must use one tightening bolt, and for every bolt, he uses two washers. He buys a bag of 20 washers for the job. After he completes the bathroom job, how many washers will be remaining in the bag?
Answer: If Edward needs to use 1 bolt per every five feet of piping, then for a job requiring 40 - feet of piping, he will use 40 / 5 = 8 tightening bolts. If for every 1 bolt he uses two washers, then he will need 8 * 2 = 16 washers to complete the job. if he buys a bag containing 20 washers, and removes 16, he will have 20 - 16 = 4 washers remaining in the bag. The answer is 4.
