Q: A school has 1000 students. Half of the students were taken on a trip to the nearby beach. Half of the remaining students were sent home. How many students are still in the school?
A: 1000 * 1 / 2 = 500 students were taken on a trip to the nearby beach. So 1000 - 500 = 500 students were not taken to the beach. Thus, 1 / 2 * 500 = 250 students who were not taken to the beach were sent home. Thus, 500 - 250 = 250 students are still in school. The answer is 250.
Question: Noah, who loves his Grammy, calls her every week to talk about his day. If each call lasts 30 minutes and he is charged $0.05 per call minute, how much would he be billed if he makes the calls for a year?
Answer: A year has 52 weeks, so if he talks for 30 minutes every week, the total number of call hours is 52 * 30 = 1560 minutes. Since he is charged 0.05 cents per call, the total cost is 1560 * .05 = 78 dollars. The answer is 78.
[Question]Mark can jump 6 inches off the ground. Lisa can jump double the height as Mark, and Jacob can jump double the height of Lisa. If James jumps 2/3 as high Jacob, how high can James jump?

Q: Jameson has 20 medals. Five of the medals are for the track. He has two times as many swimming medals as track medals. The rest of the medals are for badminton. How many badminton medals does he have?
A: Jameson has 5 x 2 = 10 medals for swimming. He has a total of 5 + 10 = 15 medals for track and swimming. Thus, he has 20 - 15 = 5 medals for badminton. The answer is 5.
Question: There are 28 garden gnomes in a yard. Three-fourths of them have red hats, and the rest have blue hats. Half the garden gnomes have big noses instead of small noses. If six gnomes with blue hats have big noses, how many gnomes with red hats have small noses?
Answer: Half the gnomes have big noses, so 28 / 2 = 14 have big noses. Three - quarters of the gnomes have red hats, so 28 * 3 / 4 = 21 gnomes have red hats. There are 6 gnomes with blue hats and big noses, so there are 14 - 6 = 8 with red hats and big noses. Thus, there are 21 - 8 = 13 gnomes with red hats that have small noses. The answer is 13.
Q: Brittany has 3 gerbils: Puffy, Muffy, and Scruffy. Puffy weighs 5 ounces more than Muffy. Muffy weighs 3 ounces less than Scruffy. If Scruffy weighs 12 ounces, how much would the scale indicate, in ounces, if Brittany put Puffy and Muffy on the scale?
A:
Muffy weighs 12 - 3 = 9 ounces. Puffy weighs 5 + 9 = 14 ounces. If Brittany weighs both Puffy and Muffy, the scale would read 9 + 14 = 23 ounces. The answer is 23.
