ICA2: Derivative of a linear demand function Short Answer 1. Consider the following demand curve O(P) = 1.200-15p A. Calculate quantity demanded when the price is 20 (1.e., P=$20) GIPYE|200-15(70) 0()=1200-300 Q(P) = 900 B. Calculate the derivative of the demand function (as a function of P) 120 -15P ( 20 ) = 0 (- 150 ) =-15 UP/= -15 C. Evaluate the derivative of the demand function when P=$20 C. Does demand satisfy the Law of Demand when P-20? EXPLAIN E. For what range of prices (P) does demand satisfy the Law of Demand
