The interest rate is 8.6% compounded annually. Consider the following cash flow.
Year 0: (-$72)
Year 1: $0
Year 2: $105
Year 3: $140
Year 4: $197
Year 5: $238
Find the value of A --where you receive A 6 times (years 0-5)--that is economically equivalent to the preceding cash flow. HINT: This is different than the normal equal payment series because you are also receiving A in year 0.
