Solution - price P for demand D is given as P = 183 +120D - 3D2 Find D for which the price is increasing - Increasing and Decreasing Functions

Question

Price P for demand D is given as P = 183 +120D - 3D2 Find D for which the price is increasing

Solution

Price function P is given by

P=183+120D-3D^2

Differentiating w.r.t. D

"dP"/"dD"=120-6D

If price is increasing then we have

"dP"/"dD">0

120-6D >0

6D <120

D<20

if the demand is less than units then Price increases

Is there an error in this question or solution?
