Question: Samantha's last name has three fewer letters than Bobbie's last name. If Bobbie took two letters off her last name, she would have a last name twice the length of Jamie's. Jamie's full name is Jamie Grey. How many letters are in Samantha's last name?
Answer: There are 4 letters in Jamie's last name, so Bobbie's name is 4 * 2 + 2 = 10 letters long. Samantha's last name is 3 letters shorter than Bobbie's, so there are 10 - 3 = 7 letters in Samantha's last name. The answer is 7.
[Question]Grandpa Lou enjoys watching movies on the Hallmark channel, where every movie lasts 90 minutes. If, on Tuesday, he watched several full-length movies on the Hallmark channel for a total of 4 hours and 30 minutes, and then on Wednesday he watched on the same channel twice as many movies as he did on Tuesday. What is the maximum number of full-length movies Grandpa could have watched during these two days?
[Answer]4 hours and 30 minutes is the same as 4 * 60 + 30 = 270 minutes. At 90 minutes per movie, Grandpa could watch a total of 270 / 90 = 3 entire movies in 4 hours and 30 minutes. On Wednesday, he watched 2 * 3 = 6 movies. Thus, during these two days, he could have watched as many as 3 + 6 = 9 movies. The answer is 9.
Q: Roberto and Valerie are jumping rope at recess. Roberto can skip 4,200 times an hour. Valerie can skip 80 times a minute. If they jump rope for fifteen minutes straight, how many skips will they total?
A: Roberto skips 70 times per minute because 4,200 / 60 = 70. Together they skip 150 times a minute. They will skip 2,250 times because 150 x 15 = 2,250. The answer is 2250.
Question: There are 4 puppies and 3 dogs at a camp. Each dog eats twice as much food as a puppy, but each puppy eats three times as often as a dog. If a dog eats 4 pounds of food three times a day, what would be the total amount of food the dogs and puppies eat in a day?
Answer: Eating three times a day, a dog eats 3 * 4 = 12 pounds of food. Since there are 3 dogs at the camp, the total amount of food they eat is 3 * 12 = 36 pounds of food in a day. If each dog eats twice as much food as a puppy, a puppy will eat 4 / 2 = 2 pounds of food in one meal. Each puppy eats three times as often as a dog, and if a dog eats three times in a day, a puppy will eat 3 * 3 = 9 times in a day. Since a puppy eats 2 pounds of food a day, the total amount of food a puppy will eat in a day is 9 * 2 = 18 pounds of food. Four puppies in the camp eat 18 * 4 = 72 pounds of food every day. Together, the dogs and the puppies eat 72 + 36 = 108 pounds of food in a day. The answer is 108.
[Question]A carpenter is building a house. He needs 80 woodblocks to build it. If he has 8 logs that can make five woodblocks each, how many logs does the carpenter still need?
[Answer]The carpenter initially has 8 x 5 = 40 blocks of wood. So he still lacks 80 - 40 = 40 blocks of wood. Therefore he still needs 40 / 5 = 8 logs of wood. The answer is 8.
[Question]Emery looks through the drawer where her mom keeps the cookie cutters. There are 6 cookie cutters shaped like triangles, 4 square ones and 2 hexagons. How many sides are there on the cookie cutters in total?
[Answer]
The 6 triangles have 3 sides each, for a total of 6 * 3 = 18 sides. The 4 squares have 4 sides each, for a total of 4 * 4 = 16 sides. The 2 hexagons have 6 sides each, for a total of 2 * 6 = 12 sides. The total numbers of sides is 18 + 16 + 12 = 46 sides. The answer is 46.
