6. A national retailer attempts to determine a demand curve for a new product by selling it in different regions of the country for different prices. The resulting data is shown in the table below. Price ($) Annual Demand/ 10,000 population 2.00 232 2.50 135 3.00 79 3.50 4.00 46 27 The Vice President of Exponential Modeling determines that the demand can be modeled by the function D(p)=1990 e-1.075p, where p is the price in dollars and D(p) is the annual demand per 10,000 population. Use the model equation to estimate the demand if the price is set at $2.8.
