Lucy plans to purchase potato chips for a party. Ten people will be at the party, including Lucy. The potato chips cost 25 cents per pound. How much will Lucy pay (in dollars) for the potato chips if she wants each person to get 1.2 pounds?
Let's think: Lucy needs to purchase 10 x 1.2 = 12 pounds of potato chips. So, Lucy will pay 12 x 25 = 300 cents for it. Since there are 100 cents in $1, thus, Lucy will pay 300 / 100 = 3 dollars.. The answer is: 3.

Gentry assembled a new 24 foot round pool in her backyard. To fill the pool with water, she used four hoses. Two of the hoses each deliver water at a rate of 2 gallons per minute. The other two hoses each deliver water at a rate of 3 gallons per minute. With a volume of 15,000 gallons, how many hours will it take to fill the pool?
Let's think: Each of the two hoses delivers water at a rate of 2 gallons per minute, for a combined total of 2 * 2 = 4 gallons of water per minute. The other two hoses each deliver water at a rate of 3 gallons per minute, for a combined total of 2 * 3 = 6 gallons of water per minute. Thus, all four hoses deliver a combined total of 4 + 6 = 10 gallons of water per minute. With a volume of 15,000 gallons, it would take 15,000 / 10 = 1500 minutes to fill the pool. Converting to hours, it will take 1500 / 60 = 25 hours to fill the pool.. The answer is: 25.

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?
Let's think: 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.

There are 235 books in a library. On Tuesday, 227 books are taken out. On Thursday, 56 books are brought back and 35 books are taken out again on Friday. How many books are there now?
Let's think:
On Tuesday, 227 books were taken, so there are 235 - 227 = 8 books left. 56 books were brought back on Thursday, so there are 8 + 56 = 64 books in the library. Finally, 35 books are taken out on Friday, leaving 64 - 35 = 29 books available.. The answer is: 29.
