Jaguar Holdings Company must choose between solar and an electric$-$powered forklift truck for moving materials in its factory. Because both forklifts perform the same function, the firm will choose only one. $($They are mutually exclusive investments.$)$ The solar truck will cost more but will be less expensive to operate; it will cost $$80,000,$ whereas the electric$-$powered truck will cost $$70,000.$ The life for both types of truck is estimated to be $10$ years, during which time the net cash flows for the solar$-$powered truck will be $$20,000$ per year, and those for the electric$-$powered truck will be $$12,000$ per year.

$1)$ Calculate the NPV and IRR for each type of truck and decide which to recommend.
