Samantha has been working for a law firm and earning an annual salary of $90,000. She decides to open her own practice. Her annual expenses were $15,000 for office rent, $1,700 for supplies, $800 for utilities, and a $30,000 salary for a secretary/bookkeeper. Samantha covered her start-up expenses by withdrawing $20,000 from her saving account on which she was earning annual interest of $500. (The $20,000 was spent on furniture and at the end of the year the furniture is still in the office, assuming there is no depreciation). Her practice generated $150,000 revenue in the first year.
