Tony tries to drink more water, so he has been tracking how much water he drinks. Yesterday, he drank 48 ounces of water, which is 4% less than what he drank two days ago. How much water did Tony drink two days ago? Give me reasons, before answering the question
Tony drank yesterday 100% - 4% = 96% of what he drank two days ago. Since 96% is 48 ounces, then every 1% is equal to 48 / 96 = 0.5 ounces of water. So, Tony drank 0.5 x 100 = 50 ounces two days ago. So the final answer is 50.
