Question: John decided to buy 10 pins for himself. They are normally $20 each but they were on sale for 15% off. How much did he spend on pins?
Answer: Step-by-step reasoning process: The sell reduced the price of each pin by 20 * .15 = $3. So he paid 20 - 3 = $17 per pin. So the total cost was 17 * 10 = $170.
So the answer is 170.

Question: Ray has 95 cents in nickels. If Ray gives 25 cents to Peter, and twice as many cents to Randi as he gave to Peter, how many nickels does Ray have left?
Answer: Step-by-step reasoning process: Ray gave 25 * 2 = 50 cents to Randi. Ray has 95 - 25 - 50 = 20 cents in nickels left. Ray has 20 / 5 = 4 nickels.
So the answer is 4.

Question: Baez has 25 marbles. She loses 20% of them one day. Then a friend sees her and gives her double the amount that Baez has after she lost them. How many marbles does Baez end up with?
Answer:
Step-by-step reasoning process: She loses 5 marbles because 25 x .2 = 5. She has 20 marbles after this because 25 - 5 = 20. Her friend gives her 40 marbles because 20 x 2 = 40. Adding those marbles to the 20 she had before, she ends up with 40 marbles + 20 marbles = 60 marbles.
So the answer is 60.
