conversations.value: Can you explain how to solve this math problem: Martin went to a store to buy a new television set. He decided to spend no more than $1,000 and the sales clerk offered him the TV for $100 less and an additional 20% off. How much lower was the price of the television than the amount Martin decided to spend?
conversations.from: assistant
conversations.value: The seller has offered him the TV for 1000 - 100 = $900.
  The discount on the television was 900 * 20/100 = $180.
  The final price of the television is therefore 900 - 180 = $720.
  Martin was able to save 1000 - 720 = $280.
