Q: It takes Roque two hours to walk to work and one hour to ride his bike to work. Roque walks to and from work three times a week and rides his bike to and from work twice a week. How many hours in total does he take to get to and from work a week with walking and biking?
A: Roque takes 2 * 3 = 6 hours a week to walk to work. Roque takes 6 * 2 = 12 hours a week to walk to and from work. Roque takes 1 * 2 = 2 hours a week to bike to work. Roque takes 2 * 2 = 4 hours a week to bike to and from work. In total, Roque takes 12 + 4 = 16 hour a week to go to and from work. The answer is 16.

Q: Jamal bought 4 half dozen colored crayons at $2 per crayon. What was the total cost of the crayons that she bought?

Q: Milo's parents tell him that he can win cash rewards for good grades. He will get $5 times the average grade he gets. He gets three 2s, four 3s, a 4, and a 5. How much cash does he get?
A:
His total score is 27 because (3 x 2) + (4 x 3) + 4 + 5 = 27. His total number of grades is 9 because 3 + 4 + 1 + 1 = 9. His average grade is a 3 because 27 / 9 = 3. He earns $15 because 5 x 3 = 15. The answer is 15.
