dp The marginal price dx at x units of demand per week is proportional to the price p. There is no weekly demand at a price of $50 per unit [p(0)=50], and there is a weekly demand of 8 units at the price of $23.68 per unit [p(8) = 23.68]. Use the given information to answer the questions. a) Find the price-demand equation. p(x) = (Type an exact answer in simplified firm. Round all decimal values to the nearest hundredth as needed.) b) At a demand of 10 units per week, what is the price? p(10) $ (Round to the nearest cent as needed.) c) Graph the price-demand equation for 0 x25.
