Suppose you own a new business and after a few rough years you now are making a solid profit of $150,000 per year and have built up some savings as well. While your business is successful, you realize that in order to expand and remain competitive you are going to have to raise a lot of money to invest in some new machinery and new stores. You have to decide between using your savings to finance your expansions and machinery upgrades, taking out a bank loan, or selling a portion of your equity to new investors. Explain the pros and cons of each of these three options in this situation.
