Explanation of Solution

A.

Given Information:

There are 5 regular lines ad 1 express lines.

Average time a customer spends in a regular line = 11 min which means that one regular line can handle 5.45 customers per day.

Average time a customer spends in an express line = 4 min which means that one express line can handle 15 customers per day.

Shift duration = 12 hours per day

Thus,

The capacity of 5 regular lines = 5.45 × 12 × 5 = 327 customers per day

The capacity of 1 express lines = 15 × 12 × 1 = 180 customers per day

Therefore, the maximum capacity of store = (327 + 180) = 507 customers per day.

Explanation of Solution

Given Information:

There are 5 regular lines ad 1 express lines.

Average time a customer spends in a regular line = 11 min which means that one regular line can handle 5.45 customers per day.

Average time a customer spends in an express line = 4 min which means that one express line can handle 15 customers per day.

Shift duration = 12 hours per day

The store’s capacity by day of the week is as follows:

    PeriodMonday
    HoursNo. of lines openCapacity (customers per day)
    9-12 noon31
    5.45 × 3 × 1 = 16.35
    12-4 PM42
    5.45 × 4 × 2 = 43.6
    4-6 PM23
    5.45 × 2 × 3 = 32.7
    6-9 PM34
    5.45 × 3 × 4 = 65.4
    Total Capacity of Regular Line (Customers per day)158.05

Since the express line is always open, and the capacity is 180 customers per day.

Therefore, the maximum capacity on Monday is 338 customers per day.

Also, the maximum capacity on Tuesday, Wednesday and Thursday will be 338 customers per day as same number of regular lines are open as on Monday.

    5.45 × 4 × 3 = 65.4
    4-6 PM25
    5.45 × 2 × 5 = 54.5
    6-9 PM35
    5.45 × 3 × 5 = 81.75
    Total Capacity of Regular Line (Customers per day)250.7

Since the express line is always open, and the capacity is 180 customers per day.
