conversations.value: I would love to understand how to solve this problem: Eunice spent $7500 on a used car, which is 25% less than the original price. What was the original price of the car?
  Can you explain?

conversations.value: The price $7500 is 100% - 25% = 75% of the original price.
  So, every 1% is equal to $7500/75% = $100.
  Hence, the original price is equal to $100/1% x 100% = $10000.
