We intend to give weight (degree of difficulty) to each support ticket, starting from 1 the easy to 5 for hard ticket, so that I can count the weight of answered tickets at the end of the month for each employee.
The calculation in the end should be an integer like this:
n = number of tickets
w = weight (1, 2, 3 , 4,5)
(n1 * w1) + (n2 * w2) + (n3 * w3) ...
