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.
