econ marginal 一問
can anyone help me with this concept of Marginal benefit and marginal cost with graph?
When goods or activities areperfectly divisible, the rule is
•do the additional∆ unit of activity X if and only if
MB(additional∆ unit | Q units) ≥
MC(additional ∆ unit | Q units)
•Let∆ approach zero, the rule becomes
MB(additional ∆ unit | Q units) = MC(additional∆ unit| Q units)
