and ′ ( ) = R x . Find the total Profit given that the total cost at zero output is zero. Given MC = + x C( x ) x dx k = k ( ) But given when x ⇒ k = ∴ C ( x ) = ( ) Given that MR = R ( x ) MR dx k k = x + k Revenue = , when x = ⇒ k = R ( x ) = x ( ) Total Profit functions P ( x ) = R ( x ) – C ( x ) P ( x ) = = Example . The marginal revenue function (in thousand of rupees ) of a commodity is Where x is the number of units sold.
