Q: Larry started off having 150 channels from his cable company. They took 20 channels away and replaced those with 12 channels. He called the company and asked if he could reduce his package by 10 more channels but add the sports package which is 8 channels. He realizes that he didn't add the supreme sports package. He calls back and that package adds 7 more channels. How many channels does Larry have?
A: He started off with 150 channels and they took 20 away and added 12 so he has 150 - 20 + 12 = 142 channels. He called and asked to reduce his 142 channels by 10 channels and added 8 sports channels so he now has 142 - 10 + 8 = 140 channels. He ordered the wrong sports package and the new one adds an additional 7 channels for a total of 140 + 7 = 147 channels. The answer is 147.
Question: Micah bought envelopes to send, and depending on the weight of the envelope he will need more stamps. If an envelope weighs more than 5 pounds, he will need 5 stamps. If it weighs less than that, it will only need 2 stamps. If he bought 52 stamps with 6 envelopes that weigh less than 5 pounds, how many envelopes in total did Micah need to buy?
Answer: Micah had to buy 6 * 2 = 12 stamps for 6 envelopes less than 5 pounds. He has 52 - 12 = 40 more stamps to buy. There are 40 / 5 = 8 envelopes that weigh more than 5 pounds. Micah needed to buy 8 + 6 = 14 envelopes. The answer is 14.
[Question]Jenny is older than Charlie by five years, while Charlie is older than Bobby by three years. How old will Charlie be when Jenny becomes twice as old as Bobby?
[Answer]Jenny is older than Charlie by 5 years who is older than Bobby by 3 years, so Jenny is older than Bobby by 5 + 3 = 8 years. Jenny will be twice as old as Bobby when he is 8 * 2 = 16 years old. Jenny is 5 years older than Charlie so when Jenny is 16, Charlie will be 16 - 5 = 11 years old. The answer is 11.
Q: In a certain forest, there are 4 species of trees: oak, pine, spruce, and birch. There is a total of 4000 trees in the forest. Spruces make up 10% of all the trees, and pines 13%. There are as many oaks as spruces and pines put together. How many birches are there in the forest?
A: There are 10 / 100 * 4000 = 400 spruces in the forest. There are 13 / 100 * 4000 = 520 pines in the forest. There are as many oaks as pines and spruces together, so there are 400 + 520 = 920 oaks. Therefore there are 4000 - 920 - 520 - 400 = 2160 birches. The answer is 2160.
Question: Harrison Elementary School is overcrowded with 1590 students, so 40% of the students are going to move to a new school. There are 3 grade levels, and each grade level needs one 20-person advanced class and the rest of the students divided evenly into 6 additional classes. How many students will there be in each normal class at the new school?
Answer: First find how many students go to the new school: 1590 students * .4 = 636 students. Then divide that number by 3 to find how many students are at each grade level: 636 students / 3 grades = 212 students / grade. Then subtract the 20 students in the gifted class: 212 students - 20 students = 192 students. Then divide that number by 6 to find the number of students in each other class: 192 students / 6 classes = 32 students / class. The answer is 32.
