Consider a Production Process with Two Inputs and Assume the Level

Multiple Choice

Consider a production process with two inputs and assume the level of one of the inputs is fixed in the short run. To determine the optimal level of the variable input you should:

A) solve the total cost equation for the level of the variable input.
B) solve the total cost equation for the level of the fixed input and substitute that into the production function.
C) solve the production function for the level of the fixed input.
D) solve the production function for the level of the variable input.
