Final answer:
The percentage of customers who complain to the front line employee can be calculated by dividing the number of customers who complain by the total number of customers and multiplying by 100.
Step-by-step explanation:
To determine the percentage of customers who complain to the front line employee, you need to know the total number of customers and the number of customers who complain. Let's assume there are 100 customers and 10 customers complain. Now, divide the number of customers who complain by the total number of customers and multiply by 100 to get the percentage:
Percentage of customers who complain = (Number of customers who complain / Total number of customers) x 100
In this case, the percentage of customers who complain would be:
(10 / 100) x 100 = 10%
