conversations.value: This math problem has got me stumped: Aleesia lost 1.5 pounds each week for 10 weeks. Alexei lost 2.5 pounds each week for 8 weeks. How many pounds did the two friends combine to lose?
  Can you show me the way?

conversations.value: Alessia = 1.5 * 10 = 15 pounds
  Alexei = 2.5 * 8 = 20 pounds
  15 + 20 = 35 pounds
  Together they lost 35 pounds.
