[Question]John decided to sell his PlayStation to buy a new computer. The computer's cost was $700 and the accessories cost was $200. The PlayStation was worth $400 but he sold it for 20% less than its value. How much money came out of his pocket?
[Answer]He loses 400 * .2 = $80 on the PlayStation. So he sells it for 400 - 80 = $320. The computer cost 700 + 200 = $900. So he was 900 - 320 = $580 out of pocket. The answer is 580.
Q: There's a sale at your favorite "Any item $10" retailer. If you buy 1 shirt you pay $10. If you buy 2, you get the second one at a 50% discount. If you buy 3, you get the third one at a 60% discount. How much money did you save if you bought 3 shirts?
A: The first shirt has no (0%) discount off the regular price ($10), therefore your discount is = 0% * $10 = $0. The second shirt has a 50% discount off the regular price ($10), therefore your discount is = 50% * $10 = $5. The third shirt has a 60% discount of the regular price ($10), therefore your discount is = 60% * $10 = $6. Therefore in total, you save $0 on the first shirt, $5 on the second one and $6 on the third one = 0 + 5 + 6 = $11. The answer is 11.
Question: Ken buys gummy vitamins. They are usually $15.00 per bottle at his grocery store, but they are currently 20% off. On top of that, he has 3 $2.00 coupons. How much will 3 bottles cost?
Answer: The vitamins are $15.00 a bottle and are currently 20% off so that’s 15 * .20 = $3.00 off. The vitamins are $15.00 and they are $3.00 off so they are now 15.00 - 3 = $12.00.

The answer is 30.
[Question]Sophie does 4 loads of laundry a week and uses 1 dryer sheet per load. A box of dryer sheets costs $5.50 and has 104 dryer sheets in a box. On her birthday, she was given wool dryer balls to use instead of dryer sheets. How much money does she save in a year not buying dryer sheets?
[Answer]She does 4 loads of laundry a week and used 1 dryer sheet per load for a total of 4 * 1 = 4 dryer sheets in a week. She used 4 dryer sheets per week for 52 weeks for a total of 4 * 52 = 208 dryer sheets. Her box of dryer sheets has 104 sheets so she needs 208 / 104 = 2 boxes of dryer sheets. Each box costs $5.50 and she used 2 boxes so she now saves 5.50 * 2 = $11.00 by not buying dryer sheets. The answer is 11.

A: After his daughter eats some candy, Boris has 100 - 8 = 92 pieces of candy. In one bowl, there are 92 / 4 = 23 pieces of candy. After Boris takes some candy for himself, there are 23 - 3 = 20 pieces of candy in one bowl. The answer is 20.
Question: The total average age of three friends is 40. Jared is ten years older than Hakimi, and Molly's age is 30. How old is Hakimi?
Answer:
The total age for the three friends is 40 * 3 = 120. If Molly's age is 30, then Jared and Hakimi have a total age of 120 - 30 = 90. Let's say the age of Hakimi is x. Since Jared is 10 years older than Hakimi, Jared is x + 10 years old. Jared and Hakimi's total age is x + (x + 10) = 90. This translates to 2x = 90 - 10. 2x = 80. Hakimi's age is x = 80 / 2. This gives us x = 40, which is Hamkimi's age. The answer is 40.
