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?
