Question: Andy harvests all the tomatoes from 18 plants that have 7 tomatoes each. If he dries half the tomatoes and turns a third of the remainder into marinara sauce, how many tomatoes are left?
Answer: First find the total number of tomatoes harvested: 18 plants * 7 tomatoes / plant = 126 tomatoes. Then divide that number by 2 to find how many tomatoes are left undried: 126 tomatoes / 2 = 63 tomatoes. Then divide that number by 3 to find how many tomatoes are turned into sauce: 63 tomatoes / 3 = 21 tomatoes. Then subtract that number from the number of undried tomatoes to find the remaining number of tomatoes: 63 tomatoes - 21 tomatoes = 42 tomatoes. The answer is 42.

Question: James creates a media empire. He creates a movie for $2000. Each DVD cost $6 to make. He sells it for 2.5 times that much. He sells 500 movies a day for 5 days a week. How much profit does he make in 20 weeks?
Answer: He sold each DVD for 6 * 2.5 = $15. So he makes a profit of 15 - 6 = $9. So each day he makes a profit of 9 * 500 = $4500. So he makes 4500 * 5 = $22,500. He makes 22,500 * 20 = $450,000. Then after the cost of creating the movie he has a profit of 450,000 - 2000 = $448,000. The answer is 448000.
[Question]Kevin has been for a run and wants to calculate how far he traveled. He ran at 10 miles per hour for half an hour, 20 miles per hour for half an hour, then ran at 8 miles per hour for 15 minutes. How many miles has Kevin run?
[Answer]At his first speed, Kevin ran 10 miles per hour * 0.5 hours = 5 miles. At his second speed, he ran 20 miles per hour * 0.5 hours = 10 miles. 15 minutes is a quarter of an hour so at his third speed, he ran 8 miles per hour * 0.25 hours = 2 miles. Therefore, Kevin ran a total of 5 miles + 10 miles + 2 miles = 17 miles. The answer is 17.
[Question]There are 10 rows of 15 chairs set up for the award ceremony. The first row is reserved for the awardees while the second and third rows are for the administrators and teachers. The last two rows are then reserved for the parents and the rest of the rows are for the students. If only 4/5 of the seats reserved for the students are occupied, how many vacant seats from the students can be given to the parents?
[Answer]
There are 1 + 2 + 2 = 5 rows that are not reserved for the students. Hence, 10 - 5 = 5 rows are reserved for the students. That is equal to 5 x 15 = 75 seats. But only 75 x 4 / 5 = 60 seats are occupied by the students. Therefore, 75 - 60 = 15 seats can be given to the parents. The answer is 15.
