Net present value$$unequal lives

Project $1$ requires an original investment of $$90,600.$ The project will yield cash flows of $$13,000$ per year for $8$ years. Project $2$ has a computed net present value of $$18,100$ over a $6-$year life. Project $1$ could be sold at the end of $6$ years for a price of $$66,000.$

Use the Present Value of $$1$ at Compound Interest and the Present Value of an Annuity of $$1$ at Compound Interest tables shown below.
