Scenario $1$: Barry's Tire Service completed $100$ tire changes, six brake jobs, and $16$ alignments in an eighthour day with his standard crew of six mechanics. A brake specialist costs $$16$ per hour, a tire changer costs $$8$ per hour, and an aligment. mechanic costs $$14$ per hour. The materials cost for a day was $$2000,$ and overhead cost was $$500$

Tile changer cost $=6$ mechenics $-81$ haw $=48$

$\frac{31\mathrm{.}70}{?}$ hour What is the shop's labor productivity if the retail price for each respective service is $$60,$ $$150,$ and $$40?$ Show your answer as dollars per labor hour, rounded to one decimal place.

Brake Sfecialist Cost: bnechanies. I$6/$hown $=128$ alagonont Mrectonic Cost: bnedranics $-\frac{14}{?}$ hown $=84$

Total labor Cost $=48+128+84=250$ Etal Rev $=6000+900+640=7540$ Labor Productivity $=$ Tot rev$/$Tot Lab cost

$=\frac{7540}{250}=\frac{31\mathrm{.}70}{h}$our

What is the multifactor productivity, if the crew consisted of two of each type mechanic? Show your to two decimal places.
