The aforementioned definition, indicates that the marginal cost is the increase in the cost recorded when an additional unit of a certain good is produced. <u>In other words, the marginal cost reflects the rate of variation of the cost divided by the change in the level of production.</u>
<u>The curve representing the evolution of marginal cost has the shape of a concave parabola, due to the law of diminishing returns.</u>
In the graph, the marginal cost curve has the following values:
- For one pie, it's $ 1.00
- For two pies, the curve decreases and it's $ 0.60
- For three pies, the curve keeps decreasing and it's $ 0.30
- For four pies, the curve begins to increase and it's $0.60
- For five pies, the curve continue increasing and it's $ 1.40
