S. tonsider yourself as an entrepreneur at the mall selling 300 donuts a day at $5 each. When you raised the price to $7 each, the sale dropped to 150 donuts per day. 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 $200 per day and the cost of each donut is .70C. What would be the price of the donut to maximize the profit?
