JNU SIS 2021 Question 14: Monopoly and price discrimination

The monopolist faces a demand curve given by D(p)=10p−3D(p) = 10p^{-3}D(p)=10p−3. Its cost function is c(q)=2qc(q) = 2qc(q)=2q. What are the optimal level of output and price?

Plain-text version

The monopolist faces a demand curve given by D(p) = 10p⁻³. Its cost function is c(q) = 2q. What are the optimal level of output and price? (A) q = 10, p = 2 (B) q = 10⁻³, p = 10^(4/3) (C) q = 10 x (3⁻³), p = 3 (D) q = 50, p = 2

Also written as: The monopolist faces a demand curve given by D(p) = 10p^(-3). Its cost function is c(q) = 2q. What are the optimal level of output and price?
