One ham sandwich requires 2 slices of cheese, and one grilled cheese sandwich requires 3 slices of cheese. She uses a total of 50 slices of cheese to make the sandwiches.

Question: A local bookshop is selling off its old inventory in order to bring in newer books. They currently have 743 books in their store. They sold 37 books in-store on Saturday and sold 128 books online. On Sunday, they sold twice as many books in-store and increased their online sales by 34 books. They also received a shipment of 160 books. How many books do they currently have?
Answer: 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. The answer is 502.
