The marginal price dp at x units of demand per week is proportional to the price p. There is no weekly demand at dx a price of $100 per unit [p(0) = 100], and there is a weekly demand of 6 units at the price of $55.52 per unit [p(6)=55.52]. Use the given information to answer the questions. a) Find the price-demand equation. p(x) = (Type an exact answer in simplified form. Round all decimal values to the nearest hundredth as needed.)
