Mary Graham has worked as a real estate agent for Piedmont Properties for 15 years. Her annual income is approximately $100,000 per year. Mary is considering establishing her own real estate agency. She expects to generate revenues during the first year of $2,000,000. Salaries paid to her employees are expected to total $1,500,000. Operating expenses (i.e., rent, supplies, and utility services) are expected to total $250,000. To begin the business, Mary must borrow $500,000 from her bank at an interest rate of 15 percent. Equipment will cost Mary $50,000. At the end of one year, the value of this equipment will be $30,000 even though the depreciation expense for tax purposes is only $5,000 during the first year.
