Answer this question:One logger can cut down 6 trees per day. The forest is a rectangle measuring 4 miles by 6 miles, and each square mile has 600 trees. If there are 30 days in each month, how many months will it take 8 loggers to cut down all the trees?
First find the total area of the forest: 4 miles * 6 miles = 24 square miles. Then find the total number of trees in that area: 600 trees / square mile * 24 square miles = 14400 trees. Then find the number of trees all the loggers can cut down in one day: 8 loggers * 6 trees / logger = 48 trees. Then divide the total number of trees by the number cut down per day to find the number of days it takes to clear the forest: 14400 trees / 48 trees / day = 300 days. Then divide the time in days by the number of days per month to find the time in months: 300 days / 30 days / month = 10 months.
The answer is 10.

Answer this 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?
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.
