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. Let's think first. Chain of thought:
User
There are 2 * 1,000 ml = 2,000 ml in a 2 - liter bottle of soda. A 2 - liter bottle of soda lasts 2,000 / 500 = 4 days.
Therefore, the answer is 4.
