Solution;

Marginal coast is change in price that comes with producing an additional unit .

Hence:

MC=C(x)MC=C'(x)

Given;

C(x)=0.375x30.99x2200x+60000C(x)=0.375x^3-0.99x^2-200x+60000

Differentiate to get the marginal cost ;

MC=C(x)=1.125x21.98x+200MC=C'(x)=1.125x^2-1.98x+200

x=100x=100

Hence by direct substitution;

MC=1.125(1002)1.98(100)+200MC=1.125(100^2)-1.98(100)+200

MC=11,252MC=11,252
