GENERAL INSTRUCTIONS: ENTER YOUR ANSWER WITHOUT THE $ SIGN AND COMMA, BUT FORMATTED IN DOLLARS WITH TWO DECIMAL PLACES, for instance if you compute $77,342.6478 then ENTER 77342.65 AS YOUR ANSWER. DO NOT ROUND IN YOUR CALCULATION STEPS (use calculator memory functions) TO AVOID ROUNDING ERRORS. There is a little bit of tolerance built into accepting/rejecting your answer, but if you round in your intermediate calculations you may be too far off. What is the present worth of the following stream of cash flows? An annuity that starts 7 years from now and pays $6,000 per year for 3 years (3 payments of $6,000). Assume 12% interest rate. (Note: nothing is paid in years 1-7. The first payment is received at the end of year 8. The last payment is received at the end of year 10.)
