conversations.value: I would love to understand how to solve this problem: Brad wanted to set up a lemonade stand to earn some money.  Every gallon of lemonade would yield 16 glasses.  He figured it would cost him $3.50 to make every gallon of lemonade.  He made 2 gallons to sell and decided he would sell each glass for $1.00  He drank 5 glasses while sitting in his stand.  He sold all but 6 glasses of lemonade.  How much net profit did Brad earn?
  Can you explain?

conversations.value: He made 2 gallons and each gallon had 16 glasses so 2*16 = 32 glasses
  He drank 5 glasses and had 6 left over which means he would not earn money on 5+6 = 11 glasses
  The total revenue would come from 32-11 = 21 glasses
  Each gallon cost $3.50 to make so the total cost was 2*3.50 = $7.00
  He sold 21 glasses at $1.00 per glass for a total of 1*21 = $21.00
  When you take his earnings of $21.00 and subtract the cost of $7.00 his total net profit was 21-7 = $14.00
