Question: James wants to build a 16-foot by 20-foot quilt. He uses patches that are each 4 square feet. The first 10 patches cost $10 each and then each patch after that cost half as much. How much do the patches for the quilt cost?
Answer: The patch is 16 * 20 = 320 square feet. So he needs 320 / 4 = 80 patches. The first 10 patches cost 10 * 10 = $100. He gets a discount on the next 80 - 10 = 70 patches. They each cost 10 / 2 = $5. So in total they cost 70 * 5 = $350. That means in total he paid 100 + 350 = $450. The answer is 450.
[Question]Charlie can make 5350 steps while running on a 3-kilometer running field. If he can run around the field 2 1/2 times during a running session, how many steps was he able to make?
[Answer]Charlie's steps for 3 kilometers is 5350 x 2 = 10700 steps were made when he run twice the field. Since he has run half of the field 5350 / 2 = 2675 steps were made when he runs half of the 3 - kilometer field. Therefore, Charlie was able to make 10700 + 2675 = 13375 steps for the 2 and a half run around the field. The answer is 13375.
Q: Lauren wanted to make burgers and fries for dinner. She needed a few things from the grocery store and bought the following: 2 pounds of hamburger meat that was on sale for $3.50 a pound. 1 pack of hamburger buns for $1.50. A head of lettuce for $1.00 and a large 1.5-pound tomato that was priced at $2.00 per pound. She also needed a jar of pickles that cost $2.50 and she had a $1.00 off coupon for that item. How much change would Lauren get back if she paid with a $20 bill?
A: She bought 2 pounds of hamburger meat at $3.50 per pound so 2 * 3.50 = $7.00. The tomato weighed 1.5 pounds and cost $2.00 per pound so 1.5 * 2 = $3.00. When you add up all her items she spent 7 + 1.50 + 1 + 3 + 2.50 = $15.00. Her items added up to $15.00 and she had a $1.00 coupon off pickles so 15 - 1 = $14.00. She paid with a $20.00 bill so 20 - 14 = $6.00 in change. The answer is 6.
Question: Jerry files a lawsuit against the convenience store where he works and slipped and fell. He's asking for damages for loss of a $50,000 annual salary for 30 years, $200,000 in medical bills, and punitive damages equal to triple the medical and salary damages. If he gets 80% of what he's asking for, for much money does he get?
Answer: First find the total cost of Jerry's lost salary: $50,000 / year * 30 years = $1,500,000. Then add the cost of the medical bills: $1,500,000 + $200,000 = $1,700,000. Then triple that number to find the cost of the punitive damages: $1,700,000 * 3 = $5,100,000. Then add the cost of the medical and salary damages to find how much Jerry asked for: $1,700,000 + $5,100,000 = $6,800,000. Then multiply that number by 80% to find how much money Jerry is awarded: $6,800,000 * 80% = $5,440,000. The answer is 5440000.
[Question]Mark realizes that a lot of the friends on his friends list are people he doesn't talk to anymore. He keeps 40% of his friends list and then contacts the rest. Of those only 50% respond. He removes everyone who did not respond. If he had 100 friends how many does he have left after the removal?
[Answer]He contacted 1 - .4 = .6 of his friends. So he contacted 100 * .6 = 60 people. So he removes 60 / 2 = 30 people. So he has 100 - 30 = 70 friends left. The answer is 70.

The factory produces 90 + 70 = 160 coolers per hour. The factory works 5 * 9 = 45 hours in 5 days. The factory produces ( 90 + 160) * 45 = 11250 products for 5 days. The answer is 11250.
