Hi, basically I'm struggling to rearrange this formula to work out P1, any help would be greatly appreciated
0.103 = (P1 + 13 - 327)/327.

First you can do 13-327 as they do not both need to be there

Why don't you try multiplying both sides by 327

you want to work out P1, so you need P1 to remain on the Right Hand Side.
you can first work out what 13-327 = -314
you basically do the opposite of what it says on the right hand side - to make 327 go to the other side you have to multiply 0.103 by 327, now you have 33.681 = P1 - 314
now how will we get P1 from the equation above?

Well you need to definitely retake it man. If you want a well paid job in the future, employers will be looking for a minimum of a C grade in GCSE Maths.
