conversations.value: This math problem has got me stumped: The local salon offers mani/pedis for $40.00.  They are running a Mother's day special and offering 25% off their regular rate.  Charlotte is treating herself, her daughter and 3 granddaughters to a spa day.  How much will Charlotte spend on 5 mani/pedis?
  Can you show me the way?

conversations.value: A mani/pedi is $40.00 and they are offering 25% off so that's 40*.25 = $10.00 discount
  The mani/pedi is $40.00 and there is a $10.00 discount so each one is 40-10=$30.00
  Charlotte is treating herself and 4 other people for a total of 5 people at $30.00 each so it will cost 5*30 = $150.00
