Question: Rich is reading a 372-page book. He has already read 125 pages of the book. If he skipped the 16 pages of maps, how many more pages does he have left to read to finish the book?
Answer with step-by-step thinking: He has completed 125 pages + 16 pages = 141 pages of the book. Rich has 372 pages - 141 pages = 231 pages left.
So the answer is 231.

Question: Five adults and two children go to see a movie and buy $12 worth of concessions. The total cost of their trip is $76. If each child's ticket is $7, how much, in dollars, are the adult tickets?
Answer with step-by-step thinking: First take out the cost of the concessions. That leaves $76 - $12 = $64 for the movie tickets. Each child ticket costs $7, so two children's tickets cost $7 per child ticket * 2 child tickets = $14. To find the amount spent on adult tickets, subtract the cost of the children's tickets to get $64 - $14 = $50 for adult tickets. Divide $50 for adult tickets / 5 adults = $10 per adult ticket.
So the answer is 10.

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 with step-by-step thinking:
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.
So the answer is 4.
