Suppose the marginal cost is C′(x) = e^−0.3x , where x is measured in units of 200 items and the cost is measured in units of $10,000. Find the cost corresponding to the production interval [200, 1,000].

Round to the nearest dollar.

cost=INT marginalcost/unit* dunits

= INT e^-.3x dx over x=1 to 5
this assumes the production interval is in items, so divide by 200 to put it into units.
