been having a go at this question for my assignment and not sure if its correct or not. Asked the tutor and it took him too long to work it out that class finished and its to be handed in next tuesday so need a brainiac on here to see where Im going wrong.

tried doing it standing on my head, but it was still sideways.

got it figured out, I didnt multiply it out properly. I have 360I2 = 24-200(0.0067) it should equal 25.34 and not 22.36 doh!!
