if AC = Average Cost of production ,

TC = Total Cost of production

VC = Variable Cost of production

FC = Fixed Cost of production

Q = Quantity of goods produced

Then,

• A.AC = TC; TC = VC + FC
• B.AC = (TC) Q: TC = VC + FC
• C.AC = TC; TC = (VC)(FC) Q
• D.AC = TC- FC: VC = TC- AC
• E.AC = TC ; TC = VC + AC Q
