Melissa deposits 4800 dollars in an account paying 10.3 percent interest convertible monthly. One year later, she withdraws 250 dollars. If there are no other transactions, how long will it take (since her original deposit) for her account balance to reach 8800 dollars? (Assume simple interest between compoundings, use the monthly interest rate in the simple interest formula, and assume that a month has 365/12 days.)
