conversations.value: Ben bought a lawnmower for his garden. He paid $100 for it. After six months, the value of the mower dropped by about 25%. Over the next year, the value of the mower dropped another 20% in value. How much is Ben's lawnmower worth after this time?
  Give me a clear explanation.

conversations.value: The first value drop of the lawnmower was 25/100 * 100 = $25.
  So the lawnmower was worth 100 - 25 = $75.
  Over the next year, the value dropped another 20%, which is 20/100 * 75 = $15.
  So after all this time, Ben's lawnmower is worth 75 - 15 = $60.
