An investment is scheduled to pay $1,000 one year from now; $2,000 two years from now; $3,000 three years from now, and this pattern is expected to remain the same in perpetuity (i.e., $1,000 on t=4; $2,000 on t=5; $3,000 on t=6; etc.). If the discount rate on the project is 7% (effective annual rate), what is the present value of the investment.
