Cunningham Performance Auto, Inc., modifies

$370$ autos per year.

The manager, Pete Cunningham, 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: labour, $9000$ hours $550$

suspension and modification kits; and energy, $200000$Kwh$.$

Average labour cost last year was

$1000$each, and energy costs were

$20/$hour$,$ kits cost

$\frac{5}{k}wh.$

What is the Multifactor productivity?

$($Round to $6$ decimal places. If the answer is $0\mathrm{.}0003754$ put

$0\mathrm{.}000375)$
