Answer this question:For the family reunion, Peter is buying 16 pounds of bone-in chicken and half that amount in hamburgers. He's going to buy 2 more pounds of hot dogs than hamburgers. He's also going to buy several sides that will weigh half the amount of hot dogs. How many pounds of food will he buy?
He is buying 16 pounds of chicken and half that amount in hamburgers so he's buying 16 / 2 = 8 pounds of hamburgers. He's going to buy 2 more pounds of hotdogs than hamburgers, which are 8 pounds so he'll have 2 + 8 = 10 pounds of hot dogs. He's going to buy sides that weigh half the amount of the hot dogs so that's 10 / 2 = 5 pounds of sides. He's buying 16 pounds of chicken, 8 pounds of hamburgers, 10 pounds of hot dogs and 5 pounds of sides for a total of 16 + 8 + 10 + 5 = 39 pounds of food.
The answer is 39.

Answer this question:Madison and Gigi have to run a total of 2400 meters in gym class. The track is 150 meters around. If they each have run 6 laps, how many more laps do they have to run before they reach 2400 meters?
The have run 12 laps because 6 + 6 = 12. They have run 1,800 meters because 12 x 150 = 1,800. They have 600 more meters to run because 2,400 - 1,800 = 600. The have to run 4 more laps because 600 / 150 = 4.
The answer is 4.

Answer this question:A mad scientist created a shrink ray device that, when used on anything, would cause it to shrink by 50%. The scientist, eager to use his new invention, looked through his house for something to shrink zap. The first thing he found and zapped was his wife, who at the time was carrying a tray containing 5 cups filled with coffee. If each coffee cup held 8 ounces of fluid before being zapped, how many ounces of coffee remained after his wife and the cups filled with coffee were shrink zapped?
Before the zap, the wife held 5 cups, each with 8 ounces of coffee, for a total of 5 * 8 = 40 ounces of coffee. After the zap, the coffee cups and their contents were shrunk by 50%, for a total of 0.5 * 40 = 20 ounces of coffee.
The answer is 20.

Answer this question:A rectangular plot of private property is fenced in by a chain-link fence. The long sides of the plot are three times the length of the short sides. One short side of the fence is rusted from being hit by a sprinkler and needs to be replaced. If all the sides of the fence together are 640 feet long, how many feet of fence need to be replaced?
Let S be the length of the short side of the fence. Thus, the length of a long side of the fence is 3S. There are 2 of each side, so the whole fence is 2S + 2 * 3S = 2S + 6S = 8S long. The whole fence is 8S = 640 feet long. Thus, the short side of the fence that needs to be replaced is S = 640 / 8 = 80 feet long.
The answer is 80.
