Marginal Cost Can Be Calculated As

Multiple Choice

Marginal cost can be calculated as:

A) ∆TC/∆Q, where TC is total cost and Q is output.
B) ∆VC/∆Q, where VC is variable cost and Q is output.
C) the slope of the total cost curve.
D) ∆TC/∆Q, where TC is total cost and Q is output; ∆VC/∆Q, where VC is variable cost and Q is output; and as the slope of the total cost curve.
