For the previous question, assume that you do not have sufficient savings to cover the entire amount required to start your sunblock business. You are going to have to get external financing. A local banker whom you know has offered you a six-month loan of $20,000 at an APR of 12 percent. You will pay interest each month and repay the entire principal at the end of six months.

Assume that instead of making a single up-front investment, you are going to finance the business by making monthly investments as cash is needed in the business. If the proceeds from the loan go directly into the business on the first day and are therefore available to pay for some of the capital expenditures, how much money will you need to take from your savings account every month to run the business and keep the cash balances positive?
