Question: Gunner has a box of mittens with 20 fewer pairs than a box of plugs. He decides to put 30 more pairs of plugs into the box of plugs. If the box of mittens has 150 pairs of mittens, how many plugs are there?
Answer: Step-by-step reasoning process: Since there are 20 fewer mittens pairs than the plugs, there are 150 + 20 = 170 pairs of plugs. When Gunner decides to add 30 more plugs pairs into the box of plugs, the number of plug pairs increases to 170 + 30 = 200. Since a pair has two, the 200 pairs of plugs total 200 * 2 = 400 plugs.
So the answer is 400.

Question: Ben's new car cost twice as much as his old car. He sold his old car for $1800 and used that to pay off some of the cost of his new car. He still owes another $2000 on his new car. How much did his old car cost, in dollars?
Answer: Step-by-step reasoning process: His new car costs 1800 + 2000 = 3800 dollars. His old car cost 3800 / 2 = 1900 dollars.
So the answer is 1900.

Question: Bonnie and Samuel went to the market together. Bonnie bought 8 apples. Samuel bought 20 more apples than Bonnie. Samuel then ate half of them and used 1/7 of them to make apple pie. How many apples does Samuel have left?
Answer: Step-by-step reasoning process: Samuel bought 20 + 8 = 28 apples. Samuel ate 28 / 2 = 14 apples. Samuel used 28 / 7 = 4 to make apple pie. Samuel has 28 - 14 - 4 = 10 apples left.
So the answer is 10.

Question: Pat's stick is 30 inches long. He covers 7 inches of the stick in dirt. The portion that is not covered in dirt is half as long as Sarah's stick. Jane's stick is two feet shorter than Sarah's stick. How many inches long is Jane's stick?
Answer:
Step-by-step reasoning process: 30 - 7 = 23 inches of Pat's stick is not covered in dirt. Sarah's stick is 23 * 2 = 46 inches long. Jane's stick is 12 * 2 = 24 inches shorter than Sarah's stick. Jane's stick is 46 - 24 = 22 inches long.
So the answer is 22.
