QUESTION $2[40$ points$].$ A Doc$-$in$-$a$-$Box office, a group of family practitioners, is looking for a new location to expand their services. Three locations are identified with fixed costs. Because of diverse population profiles in these locations, patient visits, variable costs, and revenues vary in each location as shown in Table below.

$\backslash$table$[[,$A$,$B$,$C$],[$Average Revenue per Patient,$60,60,60],[$Average Variable Cost per Patient,$44,47,45],[$Average Number of Visits,$13,500,12,000,11,500],[$Fixed Costs in $$,120,000,145,000,140,000]]$

$2.$a$.$ Determine the location based on total cost.

$2.$b$.$ Determine the location based on revenue.

$2.$c$.$ Determine the location based on profit.

$2.$d$.$ Determine the sensitivity of the decision in part $($c$)$ for varying values of visits. $($Hint: Draw a graph of cost$,$ revenue, and profit.$)$
