Question: Lao is farming chickens. He can sell each chicken for $1.50. A bag of chicken feed weighs 20 pounds and costs $2. Each chicken will need 2 pounds of feed from the time it hatches to the time he sells it. If he makes $65 profit from selling chickens, how many did he sell?
Answer: Step-by-step reasoning process: A bag of feed is enough for 10 chickens because 20 / 2 = 10. Each chicken costs $.2 to raise because 2 / 10 = .2. Each chicken results in $1.3 of profit because 1.5 - .2 = 1.3. He sells 50 chickens because 65 / 1.3 = 50.
So the answer is 50.

Question: Jesse and Mia are competing in a week long race. They have one week to run 30 miles. On the first three days Jesse averages (2/3) of a mile. On day four she runs 10 miles. Mia averages 3 miles a day over the first 4 days. What is the average of their average that they have to run over the final three days?
Answer: Step-by-step reasoning process: Jesse runs 2 miles in the first three days because 3 x (2 / 3) = 2. Jesse has 18 miles left to run because 30 - 10 - 2 = 18. Jesse has to run an average of 6 miles a day because 18 / 3 = 6. Mia runs 12 miles over the first four days because 4 x 3 = 12. She has 18 miles left to run because 30 - 12 = 18. She has to run six miles a day because 18 / 3 = 6. The total they both have to run is 12 miles a day. The average they have to run per day on average is 6 miles because 12 / 2 = 6.
So the answer is 6.

Question: A porcelain vase was originally priced at $200 but went on sale for 25% off. If Donna bought the porcelain vase and paid 10% sales tax, how much did she pay in total?
Answer: Step-by-step reasoning process: Donna got $200 x 25 / 100 = $50 less for the porcelain vase. So, the porcelain vase is now $200 - $50 = $150. Donna has to pay $150 x 10 / 100 = $15 for the sales tax. Therefore, she paid $150 + $15 = $165 in total.
So the answer is 165.

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.
