Mark bought 2 pounds of tomatoes for $5 per pound and 5 pounds of apples, at $6 per pound. How much did he spend in total? Give the rationale and then the answer.
Let's think step by step. Mark bought 2 pounds of tomatoes for $5 / pound * 2 pounds = $10. Mark bought 5 pounds of apples for $6 / pound * 5 pounds = $30. Now add those two quantities to find Mark's total spending: $30 + $10 = $40.. The answer is: 40.

A 25 story building has 4 apartments on each floor. If each apartment houses two people, how many people does the building house? Give the rationale and then the answer.
Let's think step by step. If each building floor has 4 apartments, we have 25 floors * 4 apartments / floor = 100 apartments. If each apartment has 2 people, 100 apartments * 2 people / apartment = 200 people.. The answer is: 200.

Let's think step by step. To make the pizza, Kimber half as many teaspoons of salt as the number of cups of flour, meaning she needs 1 / 2 * 16 = 8 teaspoons of salt. The total number of cups of flour and teaspoons of salt she needs is 8 + 16 = 24. She also needs 10 cups of water, which means the total number of cups of water and flour and teaspoons of salt she needs is 24 + 10 = 34.. The answer is: 34.
