Question: In a shipping container, there are 10 crates. Each crate is filled with 6 boxes and each box is filled with 4 washing machines. A worker removes 1 washing machine from each box. There are no other changes. How many washing machines were removed from the shipping container?
Answer: Initially, there were 6 boxes * 4 washing machines per box = 24 washing machines in each crate. So there were 24 washing machines per crate * 10 crates = 240 washing machines in the shipping container. A worker removes 1 washing machine from each box so there are now 4 original washing machines - 1 removed washing machine = 3 washing machines in each box. This means there are 6 boxes * 3 washing machines per box = 18 washing machines in each crate. So there are now 18 washing machines per crate * 10 crates = 180 washing machines in the shipping container. The difference is how many machine washing machines were removed which is 240 initial washing machines 180 current washing machines = 60 washing machines. The answer is 60.
[Question]Susan earned $600 from babysitting over the summer. She went shopping and spent half of it on clothes. Then she spent half of what was left on books. How much money did she have left?

Q: James is trying to avoid eating too much sodium. He's making a recipe that calls for 2 teaspoons of salt and 8 oz of parmesan cheese. Salt has 50 mg of sodium per teaspoon and parmesan has 25 mg of sodium per oz. If he can't reduce the salt, how many fewer ounces of parmesan cheese does he need to use to reduce the total amount of sodium by 1/3rd?
A: First find how much sodium the parmesan has in total by multiply the amount of sodium per ounce by the number of oz: 25 mg / oz * 8 oz = 200 mg. Then use the same process to find how much sodium is in the salt: 50 mg / tsp * 2 tsp = 100 mg. Then find the total sodium in the recipe by adding the sodium from the cheese and the salt: 100 mg + 200 mg = 300 mg. Then multiply the total amount of sodium by 1 / 3 to find how much less sodium James wants: 300 mg * 1 / 3 = 100 mg. Then divide this amount by the amount of sodium per ounce of cheese to find how many fewer ounces of cheese he needs: 100 mg / 25 mg / oz = 4 oz. The answer is 4.
Question: A survey conducted by the school showed that only 20% of the 800 parents agree to a tuition fee increase. How many parents disagree with the tuition fee increase?

[Question]Every ten minutes during sunset, the sky changes to a new color. How many colors did the sky turn over the two hours of a long summer sunset if each hour is sixty minutes long?
[Answer]At 60 minutes per hour, the sunset was 2 * 60 = 120 minutes long. The sky changes color every 10 minutes, so it turned 120 / 10 = 12 colors over the summer sunset. The answer is 12.
