  Tabitha has 25 dollars. She gives her mom 8 dollars and invests half what is left in a money market. She spends some money on 5 items that costs 50 cents each. How much money does Tabitha have left?

conversations.value: Tabitha has 25-8 = 17 dollars after giving some to her mom.
  Tabitha has 17/2 = 8.5 dollars left after putting some in a money market.
  The 5 items Tabitha buys totals out to 5*0.5 = 2.50 dollars.
  Tabitha has 8.5-2.5 = 6 dollars left.
