conversations.value: Can you walk me through the solution of: Erika and her brother Rick want to buy a gift for their mother that costs $250. They have both saved money. Erika saved $155 and her brother saved only half of the cost of the gift. They also want to surprise their mother with a birthday cake that costs $25. How much money will they have left after buying their mother a gift and cake?

conversations.value: Rick's savings are half the price of the gift, which is $250/2 = $125.
  The total savings for the two siblings is $155 + $125 = $280.
  Mom's gift costs $250 + $25 for the cake = $275
  Subtracting the total cost of the gift from the total savings, we get $280 - $275 = $5 left.
