Q: Tony exercises every morning by walking 3 miles carrying a 25-pound backpack, then he runs another 10 miles without the backpack. If he walks at a speed of 3 miles per hour and runs at a speed of 5 miles per hour, how many hours each week does he spend exercising?
A: Tony walks 3 miles at 3 miles per hour for 3 / 3 = 1 hour. Tony also runs 10 miles at 5 miles per hour for 10 / 5 = 2 hours. Thus, each day he exercises for 1 + 2 = 3 hours. Over the course of one week, he exercises for 3 * 7 = 21 hours. The answer is 21.
Question: Stephanie is moving into a new apartment. She needs to figure out how many pieces of silverware she should purchase. She needs spoons, butter knives, steak knives, and forks. For herself she figures 5 of each would be sufficient. But in case she has guests, she wants to have 10 extra pieces of each type. Then she realizes that if everything is clean at the same time, that she will have too many of everything and not enough room to fit them in her kitchen silverware drawer. So she decides to purchase 4 fewer spoons, 4 fewer butter knives, 5 fewer steak knives, and 3 fewer forks. How many pieces total of all the silverware is Stephanie going to buy?
Answer: Stephanie wants to get 5 each of each type of silverware for herself. 5 spoons + 5 butter knives + 5 steak knives + 5 forks = 20 pieces of silverware. She wants 10 extra of each type for guests, 10 x 4 = 40. She decides to purchase less of each type. She was originally purchasing 15 of each type. 15 spoons - 4 less spoons = 11 spoons. 15 butter knives - 4 less = 11. 15 steak knives - 5 = 10. 15 forks - 3 less forks = 12. Stephanie is going to purchase 11 spoons, 11 butter knives, 10 steak knives, and 12 forks. 11 + 11 + 10 + 12 = 44. Stephanie is going to purchase 44 pieces of silverware. The answer is 44.

Question: Zayne sells bracelets for $5 each and two for $8. If he started with 30 bracelets and made $60 from selling bracelets for $5 each, how much in total did he make from selling his bracelets?
Answer: If the bracelets he sold at $5 made $60, he sold $60 / $5 = 12 bracelets. If the total number of $5 bracelets was 12, then the total number of bracelets he sold was 30 - 12 = 18. If he was selling a pair of bracelets at $8, he sold 18 / 2 = 9 pairs. The total amount of money he made from selling the nine pairs is $8 * 9 = $72. His total earnings from selling all of his bracelets are $72 + $60 = $132. The answer is 132.
