Question: Andrew holds a bake sale to fundraise for charity. The bake sale earns a total of $400. Andrew keeps $100 to cover the cost of ingredients. He donates half of the remaining total to the local homeless shelter, and the other half to the local food bank. Andrew also decides to donate $10 from his own piggy bank to the local homeless shelter. How much money in total does Andrew donate to the homeless shelter?
Answer: After paying off the cost of ingredients, Andrew has $400 - $100 = $300. Since half of the money goes to the homeless shelter, the shelter receives $300 / 2 = $150. After contributing some of his own money, Andrew donates $150 + $10 = $160 to the shelter. The answer is 160.
[Question]A company hires employees on a contract basis, depending on the availability of work. In a particular month, they hired 200 more employees on the first week than on the second week, and 150 fewer employees on the second week than on the third week. If the number of employees hired on the fourth week was twice the number hired in the third week, and the number of employees on the fourth week was 400, what's the average number of employees hired per week?
[Answer]The fourth week had twice the number of employees as the third week, so 400 / 2 = 200 employees on the third week. In the third week, they hired 150 fewer employees than on the second week, that is 200 - 150 = 50 employees hired on the second week. The first week had 200 more hirings than the second week, that is 50 + 200 = 250 employees. The total number of employees hired is 250 + 50 + 200 + 400 = 900. The average number of employees hired per week is 900 / 4 = 225 employees. The answer is 225.
Q: This year the Oscar swag bags include two diamond earrings that cost $6,000 each, a new iPhone that costs $2,000, and some designer scarves that each cost $1,500. If the total value of the swag bag is $20,000, how many scarves are there?
A: First find the total cost of the diamond earrings: $6,000 / earring * 2 earrings = $12,000. Then subtract the cost of the earrings and iPhone from the total cost of the bags to find the cost of all the scarves: $20,000 - $12,000 - $2,000 = $6,000. Then divide the total cost of the scarves by the cost per scarf to find the number of scarves: $6,000 / $1,500 / scarf = 4 scarves. The answer is 4.
Question: For 6 weeks in the summer, Erica treats herself to 1 ice cream cone from the ice cream truck. Monday, Wednesday and Friday she gets a $2.00 orange creamsicle. Tuesday and Thursday she gets a $1.50 ice cream sandwich. Saturday and Sunday she gets a $3.00 Nutty-Buddy. How much money does she spend on ice cream in 6 weeks?
Answer: Mon, Wed, Fri she gets a $2.00 orange creamsicle so that's 3 days * $2 / day = $6.00. Tue and Thur she gets a $1.50 ice cream sandwich so that's 2 days * $1.50 / day = $3.00. Sat and Sun she gets a $3.00 nutty - buddy so that's 2 days * $3 / day = $6.00. In one week she spends $6 + $3 + $6 = $15.00. Over 6 weeks she spends 6 weeks * $15 / week = $90.00. The answer is 90.

[Answer]First find the total number of miles Jenna drives: 400 miles / way * 2 ways = 800 miles. Then multiply that number by her pay per mile to find her total pay: 800 miles * $0.40 / mile = $320. The answer is 320.
[Question]Carla needs to drive her car to do a bunch of errands. She needs to drive 8 miles to the grocery store, 6 miles to pick up her kids from school, 12 miles to drop her kids off at soccer practice, and twice the distance from the school to soccer practice to get everyone home again. If Carla's car gets 25 miles per gallon, and gas costs $2.50, how much will Carla have to spend on gas for her trip?
[Answer]
First find the distance between soccer practice and home by multiplying the distance between soccer practice and school by 2: 12 miles * 2 = 24 miles. Then find the total distance Carla drives by adding the length of each trip: 24 miles + 12 miles + 6 miles + 8 miles = 50 miles. Then find how many gallons of gas she needs by dividing the distance of the trip by her car's gas mileage: 50 miles / 25 mpg = 2 gallons. Then multiple the gallons of gas by the price per gallon to find the total cost: 2 gallons * $2.50 = $5. The answer is 5.
