conversations.value: Owen bought 12 boxes for a total of $9/box x 12 boxes = $108.
  Six boxes contains 6 boxes x 50 masks/box = 300 face masks.
  Owen made 300 masks / 25 masks/repack = 12 repacks.
  So, his revenue for selling those repacked face masks is $5 x 12 repacks = $60.
  There are 300 masks / 10 masks/baggy = 30 baggies face masks.
  So, his revenue for that is $3/baggy x 30 baggies = $90.
  Hence, his total revenue for all the face masks is $60 + $90 = $150.
  This gives him a profit of $150 - $108 = $42.
