Question: Kendall is counting her change. She has a total of $4 in quarters, dimes, and nickels. If she has 10 quarters and 12 dimes, how many nickels does she have?
Answer: The total money from the quarters is 10 * $0.25 = $2.50. The total money from the dimes is 12 * $0.10 = $1.20. The total money from the nickels is $4 - $2.50 - $1.20 = $0.30. The number of nickels Kendall has is $0.30 / $0.05 = 6 nickels. The answer is 6.

[Answer]Ellen takes 4 * 3 = 12 hours in total to rise all balls of dough. It will take 4 * 2 = 8 more hours to bake each one. It will take her 12 + 8 = 20 hours to make all of the bread. The answer is 20.
Q: James buys a weight vest for $250. He then buys 200 pounds of weight plates for $1.2 per pound. A 200-pound weight vest would cost $700 but there is a $100 discount. How much does he save with his vest?
A: The weight plates cost 200 * 1.2 = $240. So his vest cost 250 + 240 = $490. He could get the other vest for 700 - 100 = $600. So he saved 600 - 490 = $110. The answer is 110.

[Question]June’s class has 25 students. 60% are girls and the rest are boys. 40% of the boys like playing basketball and the rest don't. The number of girls who like playing basketball is double the number of boys who don't like to. What percentage of the girls in the class like playing basketball?
[Answer]
40% of the class is boys because 100 - 60 = 40. There are 10 boys because 25x.4 = 10. 60% of the boys don't like playing basketball because 100 - 40 = 60. 6 boys don't like playing basketball because 10x.6 = 6. 12 girls like playing basketball because 6x2 = 12. There are 15 girls in the class because 25 - 10 = 15. 80% of the girls in class like playing basketball because 12 / 15 = .8. The answer is 80.
