Graded problems: 1. Carland Ltd, must choose between gas-powered 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 life for both types of truck is estimated be 15 years, during which time the net cash flows for the electric-powered truck will be $25,000 per year and those for gas-powered truck will be $11,000 per year.
