Hi JimBobBrown,

Here you are given the revenue per employee and the revenue per full time employee. If we we take the first one; the revenue per employee it means that you take the total revenue and divide by the number of employees. In equation form we can write this as,

\[\mbox{Revenue per Employee}=\frac{\mbox{Total Revenue}}{\mbox{Number of Employees}}\]

So you are given the Revenue per employee as well as the total revenue for 2010. Plugging those values in the above equation you can find the number of employees for 2010. Can you try to do part 2 yourself? It's basically the same thing but instead of the number of total employees you have number of full time employees. :)

Thanks for that, still can't 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 + 224700 = 400000
63,310,000,000 / 400,000 = 158275
Employees = 158,275

63,310,000,000 / 400,000 = 158275
Employees = 158,275

You don't have to add up both revenues since the "Revenue Per Employee" includes the "Revenue per Full Time Employee". So you just got to use the Revenue per Employee amount. :)

WoW I thought something was not making sense. but it does now many thanks Sudharaka. So follow that question 2. would be just

total / full-time =

63,310,000,000 / 224700 = 281753.4

63,310,000,000 / 224700 = 281753.4

The method is correct but note that in question 2 you have to find the number of full time employees in 2008.
