conversations.value: I would love to understand how to solve this problem: 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?
  Can you explain?
conversations.from: assistant
conversations.value: 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.
