You own a burrito food truck and are considering selling at two different locations. Selling outside the library, you profit $2.80 per burrito sold, and typically sell 450 burritos in a day. Selling outside the shopping district, you only sell 400 burritos a day, but you believe you may be able to increase your prices at this location without decreasing the number of burritos sold. Question: At what profit per burrito does selling outside the shopping district become more profitable?
