I need help with this problem. Please help me solve it step by step, not using Excel. Thank you!

You have successfully started and operated a company for the past 10 years. You have decided that it is time to sell your company and spend time on the beaches of Hawaii. A potential buyer is interested in your company, but he does not have the necessary capital to pay you a lump sum. Instead, he has offered $500,000 today and annuity payments for the balance. The first payment will be for $160,000 in three months. The payments will increase at 1.6 percent per quarter and a total of 20 quarterly payments will be made. If you require an EAR of 8 percent, how much are you being offered for your company? (Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.)
