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?
