Solutions

 MC=dTCdQMC=\frac{dTC}{dQ}


TC=AC×QTC = AC \times Q


a)AC=1.5Q+4+46Qa)AC = 1.5Q + 4 + 46Q


Differentiate the AC function


TC=1.5Q2+4Q+46Q2TC=1.5Q^{2}+4Q+46Q^{2}


MC=3Q+4+98QMC=3Q+4+98Q


MC=101Q+4MC=101Q+4



b)AC=160Q+53Q+2Q2b)AC=160Q+5-3Q+2Q^{2}


MC=dTCdQMC=\frac{dTC}{dQ}


TC=AC×QTC=AC\times Q


TC=160Q2+5Q3Q2+2Q3TC=160Q^{2}+5Q-3Q^{2}+2Q^{3}


MC=320Q+56Q+6Q2MC=320Q+5-6Q+6Q^{2}


MC=314Q+5+6Q2MC=314Q+5+6Q^{2}
