Tom eats a pound of carrots and twice as much broccoli. If carrots have 51 calories per pound and broccoli has 1/3 that many calories, how many calories did he eat in total? Give the rationale and then the answer.
Let's think step by step. He ate 2 * 1 = 2 pounds of broccoli. There are 51 / 3 = 17 calories in each pound of broccoli. So he ate 2 * 17 = 34 calories of broccoli. He ate 1 * 51 = 51 calories of carrots. So in total he ate 51 + 34 = 85 calories.. The answer is: 85.

Leila bought a living room set consisting of a sofa worth $1,250, 2 armchairs costing $425 each and a coffee table. The total amount of the invoice is $2,430. What is the price of the coffee table? Give the rationale and then the answer.
Let's think step by step. The price of 2 armchairs is $425 x 2 = $850. Mrs. Dubois will pay $850 for the 2 seats. Thus the Coffee table price is $2,430 – ($1,250 + $850) = $2,430 – $2,100 = $330.. The answer is: 330.

Candied yams fly off the shelf during the holiday season. The store buys them in bulk boxes of 25 packages. If every third shopper buys a package of candied yams, how many bulk boxes of candied yams will the store need to order for their 375 predicted holiday shoppers? Give the rationale and then the answer.
Let's think step by step. Every third shopper buys a package of candied yams, so the store will need 375 / 3 = 125 packages. At 25 packages per bulk box, the store will need 125 / 25 = 5 bulk boxes of candied yams.. The answer is: 5.
