DC Electronics uses a standard part in the manufacture of several of its radios. The cost of producing 30,000 parts is $90,000, which includes fixed costs of $33,000 and variable costs of $57,000. The company can buy the part from an outside supplier for $2.50 per unit, and avoid 30% of the fixed costs.
