well, they currently have 60 computers, so ...
24
64
24
1/4 fewer computer of 80 employee means four-quarter of 80 employees, we calculate that by 1/4*80 = 20 (computer)
20 computers which are not enough for an old employee
to know how many computers to buy to cover old employee
80-20=60 computers
the question continues if the company hire 5% more employee(which is an increase in the employee)
5% of 80 = 4
4 (new employee)
old employee(84) plus + new employee(4) = 84
to get how many computer to cover but new and old employees
84-60 =24

recall, the question says each employee to has one computer
total employee = 84
total computer 60 old employee computers plus 24 additional computers = 84

therefore 24 is the answer
a company has 10 employees. each employee works on a different computer. each day, the company selects 3 employees and monitors their computer activity. in how many ways can this be done
To determine the number of ways to select 3 employees out of 10 for computer monitoring, we can use the combination formula:

C(n, r) = n! / ((n-r)! * r!)

Where n is the total number of employees and r is the number of employees to be selected.

Using this formula, we can calculate:

C(10, 3) = 10! / ((10-3)! * 3!)
= 10! / (7! * 3!)
= (10 * 9 * 8) / (3 * 2 * 1)
= 120

Therefore, there are 120 ways to select 3 employees out of 10 for computer monitoring.
