Munson Performance Auto, Inc., modifies $375$ autos per year. The manager, Adam Munson, is interested in obtaining a measure of overall performance. He has asked you to provide him with a multifactor measure of last year$$s performance as a benchmark for future comparison. You have assembled the following data. Resource inputs were labor, $10,000$ hours; $500$ suspension and engine modification kits; and energy, $100,000$ kilowatt$-$hours. Average labor cost last year was $$20$ per hour, kits cost $$1,000$ each, and energy costs were $$3$ per kilowatt$-$hour. What do you tell Mr$.$ Munson?
