An investment pays $2,100 per year for the first 7 years, $4,200 per year for the next 7 years, and $6,300 per year the following 8 years (all payments are at the end of each year). If the discount rate is 8.20% compounding quarterly, what is the fair price of this investment? Work with 4 decimal places and round your answer to two decimal places. For example, if your answer is $345.667 round as 345.67 and if your answer is .05718 or 5.718% round as 5.72.
