Question: Amelia has $60 to spend on her dinner at a restaurant. The first course costs $15 and the second course $5 more. The cost of the dessert is 25% of the price of the second course. How much money will Amelia have left after buying all those meals?
Answer: The second course cost Amelia $15 + $5 = $20. The dessert cost 25 / 100 * $20 = $5. That leaves Amelia with $60 - $15 - $20 - $5 = $20. The answer is 20.

Q: Catherine had an equal number of pencils and pens. If she had 60 pens and gave eight pens and 6 pencils to each of her seven friends and kept the rest for herself, how many pens and pencils did she have left?
A: Catherine gave eight pens to each of her seven friends, a total of 8 * 7 = 56 pens. She remained with 60 - 56 = 4 pens. When she also gave 6 pencils to each of her seven friends, she gave away 6 * 7 = 42 pencils. Since she had the same number of pencils as pens, she remained with 60 - 42 = 18 pencils. The total number of pens and pencils that Catherine remained with is 4 + 18 = 22. The answer is 22.
Question: Melody has three dogs. Each dog eats 1/2 of a pound of dog food twice a day. If Melody bought 30 pounds of dog food, how many pounds of dog food are left after a week?
Answer: Each dog eats 1 / 2 x 2 = 1 pound of dog food each day. So the three dogs eat a total of 1 x 3 = 3 pounds each day. That is 3 x 7 = 21 pounds in a week. Therefore, 30 - 21 = 9 pounds of food are left after a week. The answer is 9.
[Question]While passing by a store, Miley noticed that a bag that cost $150 last week is now on sale for $135. What percent is the discount?
[Answer]The bag is now sold for $150 - $135 = $15 less. The discount is 15 / 150 = 1 / 10. Thus, the percent discount is 1 / 10 x 100% = 10%. The answer is 10.
