Munson Performance Auto, Inc., modifies $325$ 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, $10,500$ hours; $500$ suspension and engine modification kits; and energy, $110,000$ kilowatt$-$hours. Average labor cost last year was $$30$ per hour, kits cost $$1,000$ each, and energy costs were $$3$ per kilowatt$-$hour. What do you tell Mr$.$ Munson?

Multifactor productivity is calculated by combining the input units as shown here:

Productivity $=\frac{\text{O}\text{u}\text{t}\text{p}\text{u}\text{t}}{\text{L}\text{a}\text{b}\text{o}\text{r}+\text{M}\text{a}\text{t}\text{e}\text{r}\text{i}\text{a}\text{l}+\text{E}\text{n}\text{e}\text{r}\text{g}\text{y}+\text{C}\text{a}\text{p}\text{i}\text{t}\text{a}\text{l}+\text{M}\text{i}\text{s}\text{c}\text{e}\text{l}\text{l}\text{a}\text{n}\text{e}\text{o}\text{u}\text{s}}.$

To aid in the computation of multifactor productivity, the individual inputs $($the denominator$)$ can be expressed in dollars and summed as shown below: hours
