conversations.value: Liam and Claire picked and sold oranges to save for their mother's birthday gift. Liam picked 40 oranges and sold them at $2.50 for 2 while Claire picked 30 oranges and sold them at $1.20 each. If all of their oranges were sold, how much are they going to save for their mother's birthday gift?
  Can you solve this problem?

conversations.value: Liam sold 40/2 = 20 sets of oranges that cost $2.50 for each set.
  So, Liam earned $2.50 x 20 = $50.
  Claire earned $1.20 x 30 = $36.
  Thus, they were able to save $50 + $36 = $86 for their mother's birthday gift.
