Recall that to find the cost to produce the th unit in a production process, we calculate the difference
where is the cost of producing units.

The total cost (in dollars) for a fast food franchise of producing thousand hamburgers might be

Find the exact cost of producing the 2,001st burger. Be careful though. The units for are thousand of hamburgers. The 2,001st burger is represented by 2.001!

Exact cost of 2,001st burger = $

Use marginal cost to approximate the cost of producing the 2001st burger.

Approx. cost of 2001st burger = $
