Example
Zoe, monopolist of the lemonade market on her street, faces the following production costs
$$ C ( Q ) = 2 Q $$Her marginal cost is
$$ MC ( Q ) = \frac{d C ( Q )}{d Q} = 2 $$It costs Zoe $2 to produce one additional liter of lemonade.
Question
Zoe's costs function is `C ( Q ) = 63 Q+ 47`.
What is her marginal cost of production?
Zoe's marginal cost are
$$ MC ( Q ) = \frac{d C ( Q )}{d Q} = 63 $$
