According to the Lerner Elasticity Rule, if the price elasticity of demand, in absolute value terms, is 5, and the cost of producing the good is $10, the monopolist should price the product at P= [?] dollars.
According to Lerner index we have,
(P-MC)/P = -1/elasticity
=> (P-10)/P = 1/5
=> 5P - 50 = P
=> 4P = 50
=> P = 50/4 = 12.5
Thus, the answer is Price is 12.5
