conversations.value: This math problem has got me stumped: Janeth bought 5 bags of round balloons with 20 balloons in each bag. She also bought 4 bags of long balloons with 30 balloons in each bag. While blowing up the balloons, 5 round balloons burst. How many balloons are left?
  Can you show me the way?

conversations.value: Janeth bought 5 x 20 = 100 round balloons.
  She bought 4 x 30 = 120 long balloons.
  So, she has a total of 100 + 120 = 220 balloons.
  Since 5 round balloons burst, then there are only 220 - 5 = 215 balloons left.
