Suppose you will be receiving payments of $140, $180, $220, $260, and $300 at the end of months 2, 3, 4, 5 and 6, respectively, beginning from now (You will get $140 at the end of the second month, $180 at the end of the third, ... , $300 at the end of the sixth month from now). The interest rate is 6% per month. Draw the cash-flow diagram for this cash flow, and find its equivalent present value. Use a uniform gradient in your answer.
