Hi, I have a question about the following question. How many more employees have to be on team that will work on project A if the company wants to finish project within 72 days?

In the actual assignment, there was a table and you had to use the information from the table, so let me share the info from the table below (probably not all information is relevant for this question):

Project A Overview

No employees: 18

No of days: 95

Budgeted spend ($): 32000

Actual spend ($): 30000

Question: How many more employees have to be on team that will work on project A if the company wants to finish project within 72 days?

The answer suggested is: (18*95)/72 = 23.75 ( -> rounded ca. 24); 24 - 18 = 6 -> 6 employees have to join.

I really dont understand this logic. I dont understand why you can calculate 18 employees * 95 days if 95 days are the total project days.

I would have started like this:

No of days 95/ No of employees 18 = 5.27

5.27 * 72 days = 379.44

Difference:

379.44 - 18 = 361.44

I know the correct answer, which is 6 more employees, and even from a logical perspective, 361.44 looks way too big... they certainly dont need that many people. But I dont know how to calculate it to get 6 employees.

Could you please:

- Explain me this logic or

- Share an alternative calculation to derive to the correct answer?

Please help. Thank you so much.
