Q: Christine and Rachel went strawberry picking. They want to make pies and need 3 pounds of strawberries per pie. Christine picked 10 pounds of strawberries and Rachel picked twice as much as Rachel. Together, how many pies can they make?
A: Christine picked 10 pounds and Rachel picked twice as much, so Rachel picked 10 * 2 = 20 pounds of strawberries. Christine picked 10 pounds and Rachel picked 20 pounds for a combined total of 10 + 20 = 30 pounds of strawberries. They need 3 pounds of strawberries to make 1 pie and they have 30 pounds so they can make 30 / 3 = 10 strawberry pies. The answer is 10.
Question: The parking lot in front of the school has 52 parking spaces. The parking lot in the back of the school has 38 spaces. If 39 cars have parked and 1/2 of the spaces of the back are filled, how many parking spaces are still available in the school?
Answer: There are a total of 52 + 38 = 90 parking spaces in the school. Since half of the spaces are filled then, 38 x 1 / 2 = 19 cars have parked at the back. So, a total of 39 + 19 = 58 cars have parked in the school. Therefore, 90 - 58 = 32 parking spaces are still available. The answer is 32.

Q: An airline company owns 5 airplanes. Every airplane they own has 20 rows with 7 seats in each row. Each airplane makes 2 flights a day. How many passengers can the airline company accommodate each day?
A: Each airplane has 20 x 7 = 140 seats. So, the 5 airplanes can accommodate a total of 140 x 5 = 700 passengers. Therefore, the airline company can accommodate 700 x 2 = 1400 passengers each day. The answer is 1400.
Question: Mary is making a spinach quiche. She takes 40 ounces of raw spinach and cooks it until it's 20% of its initial volume. If she mixes the spinach with 6 ounces of cream cheese and 4 ounces of eggs, what is the total volume of the quiche?
Answer: First find the cooked volume of the spinach: 40 ounces * 20% = 8 ounces. Then add that to the volume of the other ingredients to find the total volume: 8 ounces + 6 ounces + 4 ounces = 18 ounces. The answer is 18.
Q: Karen packs peanut butter sandwiches in her daughter's lunch 2 randomly chosen days of the week. The other 3 school days, she packs a ham sandwich. She packs a piece of cake on one randomly chosen day and cookies the other four days. What is the probability, expressed as a percentage, that Karen packs a ham sandwich and cake on the same day?
A:
There are 5 school days in a week, so the probability Karen packs a ham sandwich is 3 / 5 and the probability she packs cake is 1 / 5. Multiply the two probabilities to find the probability both things happen: 3 / 5 * 1 / 5 = 3 / 25. Now divide 3 by 25 and multiply by 100% to express this probability as a percentage: 3 / 25 * 100% = 12%. The answer is 12.
