ABC company currently has 1/4 fewer computers than it has employees,if they currently have 80 employees and they want to hire 5% more.how many computers will they need to buy to ensure that each employees has one?

24

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

well, they currently have 60 computers, so ...

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.

To find out how many computers ABC company needs to buy, we need to follow these steps:

Step 1: Calculate the current number of computers ABC company has.

Given that ABC company currently has 1/4 fewer computers than employees, let's calculate 1/4 of the number of employees they have:

1/4 * 80 employees = 20 employees

Subtracting this from the current number of employees will give us the current number of computers:

80 employees - 20 employees = 60 computers

ABC company currently has 60 computers.

Step 2: Determine the total number of employees after hiring 5% more.

To find the number of employees after hiring 5% more, we need to calculate 5% of the current number of employees and add it to the current number of employees:

5% of 80 employees = (5/100) * 80 employees = 4 employees

Total employees after hiring 5% more: 80 employees + 4 employees = 84 employees

Step 3: Calculate the number of computers needed for each employee.

To ensure that each employee has one computer, we need to divide the total number of employees by the number of computers:

Number of computers needed for each employee = Total number of computers / Total number of employees

Number of computers needed for each employee = 60 computers / 84 employees

Number of computers needed for each employee ≈ 0.7143 (rounded to 4 decimal places)

Step 4: Determine the number of computers ABC company needs to buy.

Since we cannot have a fraction of a computer, we need to round up the previous result to the nearest whole number. This will give us the minimum number of computers needed to ensure that each employee has one:

Number of computers needed to buy = Round up(Number of computers needed for each employee)

Number of computers needed to buy = Round up(0.7143) = 1

Therefore, ABC company needs to buy at least 1 computer to ensure that each employee has one.
