Jackson Auto, Inc., modifies $3500$ autos per year. The$$manager$,$ Robert Jackson, is interested in obtaining a measure of overall performance. He has asked you to provide him with a multifactor measure of last$$year$\text{'}$s performance as a benchmark for future comparison.$$You have assembled the following data. Resource inputs$$were: labor, $100\mathrm{.}000$hours; $3500$ suspension and engine modification$$kits; and$$energy$,1,300,000$kilowatt$-$hours. Average labor cost last year was $$$$35\mathrm{.}50$ per$$hour$,$ kits cost $$$$1,400$each$,$ and energy costs were $$$$6\mathrm{.}15$ per$$kilowatt$-$hour. Calculate the multifactor productivity,
