Each notebook cost $4.00 meanwhile each pen cost $1.50. How much money will be left from Rubble after the purchase?

conversations.value: The total cost of two notebooks is $4.00 x 2 = $8.00.
  The total cost of two pen $1.50 x 2 = $3.00.
  So, the total amount Rubble spent for all the stuff was $8.00 + $3.00 = $11.00.
  Therefore, Rubble was left off with $15.00 - $11.00 = $4.00.
