Question: Bob, a marathon runner, is preparing for a race. He runs a total of 70 miles in the 3 days leading up to the race. On day one he runs 20 percent of the total miles and on day 2 he runs 50 percent of the remaining miles. How many miles does he run on day three to complete the 70 miles?
Answer: Step-by-step reasoning process: Day 1: 70(.20) = 14 miles. 70 - 14 = 56 miles remaining. Day 2:56 / 2 = 28 miles. 56 - 28 = 28 miles remaining.
So the answer is 28.

Question: Avery has 20 chickens on his farm. Each chicken lays 6 eggs. He wants to fill up egg cartons with eggs. If each egg carton can hold a dozen (12 eggs), how many egg cartons can Avery fill?

Question: Olivia gave William 10 napkins. Amelia also gives William twice the number of napkins Olivia gave him. If William had 15 napkins before, how many napkins does he have now?
Answer: Step-by-step reasoning process: After Olivia gave William 10 napkins, he ends up with 15 + 10 = 25 napkins. Amelia gives William twice the number of napkins given to him by Amelia which is 2 * 10 = 20 napkins. The total number of napkins William has now is 20 + 25 = 45 napkins.
So the answer is 45.

Question: Peggy fell off her bike and skinned her knees. She needed two bandages on her left knee and three bandages on her right knee. If the box of bandages had 8 less than two dozen bandages before Peggy skinned her knees, how many bandages were left in the box after Peggy finished putting bandages on her knees?
Answer:
Step-by-step reasoning process: Two dozen is 12 * 2 = 24. Eight less than two dozen bandages is 24 - 8 = 16 bandages. She needed two bandages on her left knee and three bandages on her right knee for a total of 2 + 3 = 5 bandages. Therefore, after Peggy finished putting bandages on her knees there were 16 - 5 = 11 bandages remaining in the box.
So the answer is 11.
