Question: The price-demand equation for home-delivered 12-inch pizzas is

p = 16.8 – 0.002x

where x is the number of pizzas delivered weekly. The current price of one pizza is $8. In order to generate additional revenue form the sale of 12-inch pizzas, would you recommend a price increase or a price decrease? [Hint: Find the values of p where the demand is elastic or inelastic.]
