Question: Mason is cleaning out all the junk in his attic. 20% of the items are useful, 10% are valuable heirlooms, and 70% are junk. If Marcus's attic has 8 useful items in it, how many junk items does it have?
Answer: First find the total number of items in the attic by dividing the number of useful items by the percentage of useful items: 8 items / .2 = 40 items. Then multiply the total number of items by the percentage that are junk to find the number of junk items: 40 items * .7 = 28 items. The answer is 28.

[Answer]Over the past five years, the sum of the temperatures was 90 + 90 + 90 + 79 + 71 = 420. To find the average temperature you divide the total temperature (420) by 5, so 420 / 5 = 84 degrees. The answer is 84.
Q: A local restaurant was offering a "Build Your Own Hot Brownie" dessert. The brownie cost $2.50 and each scoop of ice cream costs $1.00. Any syrup costs $0.50 and nuts cost $1.50. If Juanita orders the brownie with 2 scoops of ice cream, double syrup, and nuts, how much will her dessert cost?
A: She orders 2 scoops of ice cream that's $1.00 per scoop so the ice cream costs 2 * 1 = $2.00. She wants double syrup. The syrup is $0.50 so that will cost 2 * .50 = $1.00. The brownie is $2.50, the ice cream will be $2.00, the syrup will be $1.00 and the nuts will be $1.50 bringing her total to 2.5 + 2 + 1 + 1.5 = $7.00. The answer is 7.
Question: John needs to get a new seeing-eye dog. The adoption fee cost $150 for an untrained dog. It then takes 12 weeks of training which costs $250 a week. After the training, she needs certification which costs $3000 but her insurance covers 90% of that. What is her out-of-pocket cost?
Answer: The training cost 250 * 12 = $3000. The insurance pays for 3000 * .9 = $2700 for certification. That means she needs to pay 3000 - 2700 = $300. So her total cost was 150 + 300 + 3000 = $3450. The answer is 3450.

[Question]Du Chin bakes 200 meat pies in a day. He sells them for $20 each and uses 3/5 of the sales to buy ingredients to make meat pies for sale on the next day. How much money does Du Chin remain with after setting aside the money for buying ingredients?
