In Order to Solve Graphically for an Interior Cost Minimum

Multiple Choice

In order to solve graphically for an interior cost minimum of the firm, subject to the constraint of producing a particular target level of output, we:

A) shift in the isocost line as much as possible.
B) shift out the isoquant as much as possible.
C) shift the isocost line left as much as possible subject to the constraint that it touches the target isoquant at least once.
