I need the balance in Lee's account at the end of 6 years and we aren't supposed to round intermediate calculations. Obviously the answer shown in the screenshot is incorrect

Lee Holmes deposited $16,500 in a new savings account at 12% interest compounded semiannually. At the beginning of year 4, Lee deposits an additional $41,500 at 12% interest compounded semiannually. At the end of 6 years, what is the balance in Lee's account? (Do not round intermediate calculations. Round your answer to the nearest cent.) Balance $ 92,068.10
