conversations.value: To support the school outreach program, Einstein wants to raise $500 by selling snacks. One box of pizza sells for $12, a pack of potato fries sells for $0.30, and a can of soda at $2. Einstein sold 15 boxes of pizzas, 40 packs of potato fries, and 25 cans of soda. How much more money does Einstein need to raise to reach his goal?
  Work out the solution step by step.

conversations.value: Einstein collected 15 x $12 = $180 for selling pizzas.
  He collected 40 x $0.30 = $12 for the 40 packs of potato fries.
  He collected 25 x $2 = $50 for the 25 cans of soda.
  Thus, the total amount section Einstein collected was $180 + $12 +$50 = $242.
  Therefore, Einstein needs $500 - $242 = $258 more to reach the goal.
