Algebra has never been one of my academic strong points and whilst I understand the basics I'm having trouble understanding the workings of the following calculation. So yes I do have the answer but I just don't get how the final result was reached, any assistance would really be appreciated:
P = SX-VF-F (No need to drill down here, I understand the CVP formulae)
For this particular equation though the workings were revealed as follows:
10% of 2.5x = 2.5x - 2x - 800
x = 3200
Feedback would be appreciated.
