[Question]If there are two pennies in each of the twelve compartments of Roshesmina's piggy bank and she adds 6 more pennies to each compartment, calculate the total number of pennies she has?
[Answer]In each compartment, there are two pennies, and when she adds 6 pennies to each compartment, one compartment will have 6 + 2 = 8 pennies. If there are 12 compartments, and each compartment now contains 8 pennies, there are a total of 12 * 8 = 96 pennies in all the compartments. The answer is 96.
Q: Every Monday to Friday morning, Alice walks 10 miles through a large grass field to get to school. To avoid the hot afternoon sun on her way home, she walks 12 miles through a forest. When she gets home on Friday, how many miles will she have walked that week?
A: On Monday the total number of miles Alice walks to and from school is 10 + 12 = 22 miles. For the other 4 days, from Tuesday to Friday, she walks an additional 4 * 22 = 88 miles. The total number of miles she will have walked by Friday 22 + 88 = 110 miles. The answer is 110.
Question: John decides to install a ramp in his house. He needs to get permits which cost $250. After that, he hires a contractor which costs $150 an hour and the guy works for 3 days at 5 hours per day. He also pays an inspector 80% less to make sure it is OK. How much was the total cost?
Answer: The contractor works for 3 * 5 = 15 hours. That means he charged 150 * 15 = $2250. The inspector charged 2250 * .8 = $1800 less. So the inspector charged 2250 - 1800 = $450. So the total amount charged was 250 + 450 + 2250 = $2950. The answer is 2950.
[Question]Ginger is weaving mats out of colored straw. Each mat takes 20 red straws, 30 orange straws, and half as many green straws as orange straws. How many straws does she need to make 10 mats?
[Answer]First find the number of green straws each mat needs: 30 orange straws / 2 orange straws / green straw = 15 green straws. Then find the total number of straws in each mat: 15 straws + 20 straws + 30 straws = 65 straws. Then multiply that number by the number of mats to find the total number of straws Ginger needs: 65 straws / mat * 10 mats = 650 straws. The answer is 650.
Q: Carla's sheepdog rounded up 90% of her sheep, but the remaining 10% wandered off into the hills. If there are 81 sheep in the pen, how many are out in the wilderness?
A: First find the total number of sheep by dividing the number rounded up by 90%: 81 sheep / .9 = 90 sheep. Then multiply that number by 10% to find the number that are in the hills: 90 sheep * 10% = 9 sheep. The answer is 9.
Question: John injures his shoulder while lifting weights. After the injury, his bench press goes down 80%. After a bit of training, he manages to triple the weight he can bench. If he started with a 500-pound bench press, what is it now?
Answer:
He lost 500 * .8 = 400 pounds from his bench. So his bench went to 500 - 400 = 100 pounds. After training it increased to 100 * 3 = 300 pounds. The answer is 300.
