The demand for airline travel is quite sensitive to price. Typically, there is an inverse relationship between demand and price; when price decreases, demand increases, and vice versa. One major airline has found that when the price (p) for a round trip between Chicago and Los Angeles is $ 600, the demand (D) is 500 passengers per day. When the price is reduced to $ 400, demand is 1,200 passengers per day. You were asked to develop an appropriate model. Implement your model on a spreadsheet and use a data table to estimate the price that maximizes total revenue.
