[Question]Colston knows that his teacher loves drinking coffee and one day wants to see how much she drinks each week. He sees that she has a 20-ounce thermos and when she makes her coffee she pours a 1/2 cup of milk in, and then fills the coffee to the top. She does this twice a day. After the five-day school week, he decides to tell her, and when she hears how much coffee she drinks, she decides to drink 1/4 of what she normally drinks. How many ounces of coffee does she now drink a week?
[Answer]1 / 2 a cup = 4 ounces. Each thermos contains 16 ounces of coffee because 20 - 4 = 16. She drinks 32 ounces a day because 2 x 16 = 32. She drinks 160 ounces a week because 32 x 5 = 160. She starts drinking only 40 ounces because 160 / 4 = 40. The answer is 40.

Question: A machine fills 150 cans of paint every 8 minutes. How many minutes does it take this machine to fill 675 cans?
Answer: To know how many groups of 150 cans there are in 675 cans, we calculate 675 150 = 4.5. For each of these groups, 8 minutes are needed, so it takes 8 4.5 = 36 minutes. The answer is 36.
[Question]The cost of building a certain house in an area is 100,000 more than the construction cost of each of the houses in the area. But it sells for 1.5 times as much as the other houses, which sell at $320,000 each. How much more profit is made by spending the extra money to build?
[Answer]The house cost 320,000 * 1.5 = $480,000. So it is worth 480,000 - 320,000 = $160,000 more than other houses. So the profit is 160,000 - 100,000 = $60,000 more. The answer is 60000.

Question: Harry is ordering pizza. A large pizza is 14. It costs $2 per topping. He orders 2 large pizzas, each with 3 toppings. He then adds a 25% tip. What is the total cost?
Answer:
The toppings on each pizza are $6 because 3 x 2 = 6. The total for each pizza is $20 because 14 + 6 = 20. The pizzas cost $40 because 2 x 20 = 40. The tip is $10 because 40 x .25 = 10. The total is $50 because 40 + 10 = 50. The answer is 50.
