a. What is the productively measure of units of output per dollar of input, averaged over the four-year period ?
b. The company has the option of purchasing equipment for $13,000, with an operating life of five years. It would reduce labor cost to $11,000 per year. Should it consider purchasing this equipment ( using productivity arguments alone ) ?
