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? Let's think first. Chain of thought:
User
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.
Therefore, the answer is 14.
