A publicly traded consulting engine

A publicly traded consulting engineering firm pays a bonus to each engineer at the end of the year based on the company's
profit for that year. If the company's initial investment was $1.2 million, what rate of return has it made on its investment if each engineer's bonus has been $3000 per year for the past 10 years? Assume the company has six engineers and that the bonus money represents 5% of the company's profit.
