Step-by-step reasoning process: On Sunday they sold twice as many books in - store as the 37 books on Saturday so they sold 2 * 37 = 74. They sold 128 books online on Saturday and increased that number by 34 books on Sunday for a total of 128 + 34 = 162. Over the weekend they sold 37 + 128 + 74 + 162 = 401 books. They started off with 743 books and sold 401 books which brings the inventory to 743 - 401 = 342 books. They have 342 books and received a shipment for 160 bringing their inventory to 342 + 160 = 502 books.

Step-by-step reasoning process: Over 12 hours, a leak of 1.5 ounces per hour for 12 hours would generate 1.5 * 12 = 18 ounces. A bucket that can hold twice the volume leaked is 18 * 2 = 36 ounces.
The question and answer:
Question and answer: Kevin's fish tank was leaking slowly at a rate of 1.5 ounces per hour. He planned to go to the fish tank store later that day to get a new tank, but it may be as long as 12 hours before he can return home with the new tank. Therefore, to collect the leaking fluid over that time, he placed a bucket underneath the tank that could hold twice the amount of fluid that would leak over 12 hours. What size bucket, in ounces, did he use?
The answer is 36

Step-by-step reasoning process: The builder purchased 7 boxes * 11 bolts = 77 bolts. He used 77 bolts - 3 left over = 74 bolts for the project. The builder purchased 3 boxes * 15 nuts = 45 nuts. He used 45 nuts - 6 left over = 39 nuts for the project. Total for the project he used 74 bolts + 39 nuts = 113 nuts and bolts.
