Reasoning and answer: From the 200 meat pies, Du Chin makes 200 * $20 = $4000 after the sales. The amount of money he uses to buy ingredients to make pies for sale on the next day is 3 / 5 * $4000 = $2400. After setting aside money for buying ingredients, Du Chin remains with $4000 - $2400 = $1600.
The answer: 1600

Reverse engineering the question: Dana normally drinks a 500 ml bottle of soda each day. Since the 500 ml bottles are currently out of stock at the store, she buys a 2-liter bottle of soda instead. If Dana continues to drink 500 ml of soda each day, how long will the 2-liter bottle of soda last? There are 1,000 ml in 1 liter.

Reasoning and answer: First, we need to determine how many feet Ian runs in a week. We begin this by multiplying the number of laps by the number of feet per lap, performing 5 * 100 = 500 feet per day. Since there are 5 days in the period being measured, this means Ian runs 500 * 5 = 2500 feet jogged. Since it takes 25 feet of jogging to burn a calorie, this means Ian burns 2500 / 25 = 100 calories burned jogging throughout the week.
The answer: 100

Question:
Ian is looking to lose some weight. He decides to start jogging around his apartment complex every night to burn some calories. He does 5 laps around the complex every night. Each lap is 100 feet.
