First question was increase something by 35%
I got 66.5 then added that to the number (which I can't remember) atm.

Second question was the spheres in the box, I got 750cm^3

Third was the perimeter one I got 48 IIRC?

Fourth was the counters, I got 0.2 and 0.4
for the other part It was like find the amount of reds when the orange was taken out which was 50/400 or 1/8

There was a triangle question where you had to use pythogaras I got 6^2 + 8^ = 100 so the missing side was 10.
There was that circle question where you had to prove the lines were similar, I said diagonal angles in cyclic quadrilateral = 180 and then used alternate angle and then cyclic I think which gave the same angle - I have no clue if this is right though lol
There was a solve 4x^2 + x + 3 = 0 Didnt answer this but according to http://www.geteasysolution.com/0=4x%5E2-x-3 it is 1 or -0.75
Last Q was proving the sphere was larger than the cube, didn't get an answer for that.

You were looking for the hours worked by the plumbers, not the price of the work done. I think I was 4.5...

I am 100 percent sure I checked it 4 times with different methods
Why Doesn't Someone Create a Document of the Unofficial Mark Scheme and then we will all input into it, allowing us to see how we have done?
