What formulas to use to work out the following questions

[JimBobBrown]

	2007	2008	2009	2010
Total revenue ($1,000 million)	60.05	58.43	61.24	63.31
Revenue per employee ($1,000)	168.8	163.5	170.6	175.3
Revenue per full-time employee ($1,000)	198.6	197.1	210.6	224.7

1. What was the number of employees in 2010?

2. What was the number of full-time employees in 2008?

Looks like the following method was applied:

Revenue per employee = (Total revenue)/(number of employees)

and

Revenue per full-time employee = (Total revenue)/(number of full-time employees)

Use above two equations to answer your question.

Thanks for that, still cant get my head around it for some reason. So for question 1. I would add up both revenues per employee then divide total revenue by that figure?

175300 + 24700 = 400000
36,310,000,000 / 400,000 = 158275
Employees = 158,275

Do some sample calculations with the relationship provided to you in the previous reply. Did the helper say that they'd divided by total revenue by BOTH the number of (all) employess AND ALSO the number of (the subset of) full-time employees? Or was the relationship something different?

If you're not sure, create a situation with smaller numbers. Suppose that one full-time employee earned 100 for the company, while the other four part-time employees earned a total of 200 for the company. Then the total revenue is 300, and the total number of employees is five (being the one full-timer and the four part-timers).

With 300 in revenue and five employees, how much did each employee (on average) bring in? What is the per-employee amount? What did you divide by, in order to get that number? Did you really include the full-timer twice (by adding full-timers to part-timers), or did you just divide by "the number of employees" (regardless of hours worked)?

Use similar reasoning here.
