Suppose a attached’s inverse ask-for incurvation is given by P 120 .5Q and itscost equation is C 420 60Q Q2.a. Find the attached’s optimal size, worth, and use (1) by using theuse and marginal use equations and (2) by elucidation MR resembling toMC. Also stipulate a graph of MR and MC.b. Suppose instead that the attached can retail any and all of its output at thefixed chaffer worth P 120. Find the attached’s optimal output.
