A hamburger factory produces 50,000 hamburgers each week. The equipment used costs $8,000 and will remain productive for four years. The labor cost per year is $13,000. a. What is the productivity measure of "units of output per dollar of input" averaged over the four-year period? Assume that there are 52 weeks per yeaf. Round your answer to one decimal place. Productivity: hamburgers/dollar b. The company has the option of purchasing equipment for $10,500, with an operating life of five years. It would reduce labor costs to $10,000 per year. Should it consider purchasing this equipment (using productivity arguments alone)? Assume that there are 52 weeks per year, Round your answer for productivity to one decimal place. For the expensive machine, productivity is would be a hamburgers/dollar input. Because the productivity of the expensive machine is investment based on this single criterion. A fast-food restaurant has a drive-through window and during peak lunch times can handle a maximum of 60 cars per hour with one person taking orders, assembling them, and acting as cashier. The overage sale per order is $15.00. A proposal has been made to add two workers and divide the tasks among the three. One will take orders, the second will assemble them, and the third will act as cashier. With this system it is estimated that 85 cars per hour can be serviced. Assume that prevalling minimum wage is \$11.05. Use productivity arguments to recommend whether or not to change the current system. Round your answers to two decimal places. Productivity for system 1: Productivity for system 2: With the additional two workers, productivity Thus, it is to change the current system
