Given 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, and $50,000 on equipment, including maintenance. The total profit of
the salon should 150,000 –( 10,000 +
60,000 + 50,000) = $30,000. The owner could have earned more if he work at
another salon.
