Consider yourself as an entrepreneur at the Mall selling 6000 donuts a day at 50c each. When you raised the price to 70C each, the sale dropped to 5000 donuts per day. Now, assume that there is a linear relationship between the price and number of donuts sold. Further assume that there is a fix cost (overhead) of $1000 per day and the cost of each donut is 25c. What would be the price of the donut to maximize the profit?
