conversations.value: There are 7 trucks that have 20 boxes. There are 5 trucks that have 12 boxes. Each box holds 8 containers of oil. If all of the oil is evenly redistributed onto 10 trucks, how many containers of oil will each truck have?

conversations.value: Boxes of oil = 7 * 20 + 5 * 12 = 200 boxes
  Containers of oil = 200 boxes * 8 containers = 1600 containers of oil
  1600/10 = 160
  Each truck will carry 160 containers of oil.
