A construction company can lease an asset for the next four years by making lease payments that are equivalent to annual payments of $3,000 at year 0, $6000 at year 1, $7000 at year 2, $7000 at year 3 and $4000 at year 4. Use a 12% minimum acceptable rate of return. Determine the year 0 present worth lease payments, year 4 future worth lease payments and year 1 through 4 equivalent annual lease payments.
