Price–demand equation. According to economic theory, the demand x for a quantity in a free market decreases as the price p increases (see the figure). Suppose that the number x of DVD players people are willing to buy per week from a retail chain at a price of $ p is given by x = 4 , 000 0.1 p + 1 10 ≤ p ≤ 70 Figure for 95 and 96 (A) Find dx / dp. (B) Find the demand and the instantaneous rate of change of demand with respect to price when the price is $40. Write a brief interpretation of these results. (C) Use the results from part (B) to estimate the demand if the price is increased to $41.
