conversations.value: Elisa and her two friends went out to dinner. Each of them ordered a meal worth $10. Afterwards, they each had a scoop of the same kind of ice cream. If the $45 Elisa had was enough to pay for everything, what was the cost of a scoop of ice cream?
  Give me a solution to this problem

conversations.value: The three friends had meals worth 10 * 3 = 30 dollars
  If they paid for the meals only, they would have remained with 45 - 30 = 15 dollars.
  Dividing the remaining amount by the number of ice cream scoops gives 15/3 = 5 dollars.
  Each scoop of ice cream cost 5 dollars
