Question: Harry is counting the hours that he sleeps. On Monday night, he sleeps for 8 hours. On Tuesday night, he sleeps for 7 hours. On Wednesday night, he sleeps for 8 hours. On Thursday night, he sleeps for 10 hours. On Friday night he sleeps for 7 hours. What is the average number of hours that Harry sleeps in one night?
Answer: Step-by-step reasoning process: Across Monday through Friday, the total number of hours Harry sleeps is 8 + 7 + 8 + 10 + 7 = 40 hours. The total number of days from Monday through Friday is 5 days. The average number of hours Harry sleeps in one night is 40 / 5 = 8 hours.

Question: Gigi is baking cookies. The recipe for 1 batch of cookies calls for 2 cups of flour. She bakes 3 batches of cookies. If her bag of flour contains 20 cups of flour, how many more batches of cookies could Gigi make in the future with the remaining amount of flour?
Answer: Step-by-step reasoning process: For 3 batches of cookies, Gigi uses 3 * 2 = 6 cups of flour. The amount of flour remaining in the bag is 20 - 6 = 14 cups of flour. Since 1 batch uses 2 cups of flour, Gigi can make 14 / 2 = 7 more batches of cookies.
So the answer is 7.

Question: Each year a store decreased the price of a certain model of TV by $35. If the price in 2001 was $1950, what was the price in 2009?
Answer:
Step-by-step reasoning process: The period the store had the TV was 2009 - 2001 = 8 years. The TV decreased by $35 / year * 8 years = $280. So the price in 2009 was $1950 - $280 = $1670.
So the answer is 1670.
