Expert Solution
Step 1

Cost minimization can be defined as the process of reducing expenditure on those processes which are not required or are inefficient.

The formula for cost minimization is based on the rule that cost is minimized at that level where Marginal Product of Labor (MPL) divided by Wage (w) is equal to Marginal Product of Capital (MPK) divided by price of capital (r)

i.e. MPL / w = MPK / r
