The Costs of Production 3357
Scenario 13-22
Suppose that a small hair styling salon had revenues of $150,000 in a given year. The owner spent
$10,000 on
utilities, $60,000 on supplies (shampoo, conditioner, hair coloring and other chemicals,
etc.), and $50,000 on
equipment (mirrors, chairs, scissors, curling irons, etc.), including
maintenance. The owner could have earned $50,000 working at another salon.
