Price demand. The marginal price dp/dx at x units of demand per week is proportional to the price p. There is no weekly demand at a price of $100 per unit [p(0) = 100]and there is a weekly demand of 5 units at a price of $77.88 per unit [p(5) = 77.884.]
(A) Find the price demand equation.
(B) At a demand of 10 units per week, what is the price?
(C) Graph the price demand equation for 0<=x<=25.
