We are trying to find the range of the total salaries. If the salaries were between 5 and 20 inclusive, then we try to find the extreme values. Therefore, I assumed 2 scenarios.
1- 4 employees are paid the maximum (20$) and there is one who is paid 5$ --> 5 + 20*4 = 85
2- 4 employees are paid the minimum (5$) and there is one who is paid 20$ --> 4*5 + 20 = 40 _________________
