Problem $3-7($Algo$)$

Spartan Redi$-$Care is a small urgent care facility located near the university. Because of the high competition for student business, the

manager of Spartan has decided that the most effective way of competing is to emphasize short wait times. Spartan Redi$-$Care has

even gone so far as to adopt the slogan, "Get in$,$ Get better, Get out." As the facility manager, you have decided that this slogan

translates into an average customer wait time of $45$ minutes. You have collected the following data taken from a three$-$week period of

typical demand:

$c_a=3\mathrm{.}00$

$c_p=2\mathrm{.}00$

$u=60$ percent

$t_p=6\mathrm{.}8$ minutes

a$.$ What is the expected average wait time for Spartan Redi$-$Care?

Note: Do not round intermediate calculations. Round your answer to $1$ decimal place.

b$.$ If the expected average wait time is greater than what you have promised, what are some actions that you could introduce to

correct this imbalance $($be specific$)?$
