conversations.value: Harry decided to buy some balloons for his friend's birthday party. One balloon costs $0.5, and a pack of 10 balloons is cheaper and costs only $3. Finally, Harry wants to bring to the party exactly 14 balloons. How much did he need to pay for them?
  Solve this problem.

conversations.value: To buy 14 balloons, Harry should buy one pack of 10, and 14 - 10 = 4 separate balloons.
  The price of 4 balloons is 4 * 0.5 = $2.
  In total, the pack and separate balloons would cost Harry in total 3 + 2 = $5.
