Suppose the Marginal Cost Is $C ^ { \prime } ( x ) = e ^ { - 0.9 x }$

Short Answer

Suppose the marginal cost is $C ^ { \prime } ( x ) = e ^ { - 0.9 x }$ , where x is measured in units of 400 items and the cost is measured in units of $1,000. Find the cost corresponding to the production interval [1,200, 1,600]. Round to the nearest dollar.
