Question $8($Mandatory$)(10$ points$)$

Three hairstylists work in the In & Out Haircut salon, offering a limited and standardized package of shampooing and hairstyling only. It takes any one of the $3$ stylists, on average, $10$ minutes to shampoo, $15$ minutes to cut and style hair, and $5$ minutes to bill and collect from the customer. The process works as follows:

a$.$ customer checks in with Betty the receptionist $(3$ minutes average flow time$),$

b$.$ and each of the three stylists performs all three services, shampoo, cutn'style, and bill and collect, for their own individual customers.

c$.$ the steps are consecutive $-$ reception $-$ shampoo $-$ styling $-$ billing, and all customers go through all four activities.

If the billing task is shifted from the stylists to Betty at reception, what impact would that have on the process capacity, if any?
