Yeah. What book are you using? Might there be a mistake in the answers or something like that? I found at least 10 mistakes in the answers for the Edexcel FP2 book

It's not a book just a worksheet with answers given to me from uni for some summer maths work. Starting first year uni in a few weeks time. Do you think it's a mistake then??

Well, your steps seem correct to me, I haven't done much maths over the summer but going over your working I can't fault it. Maybe I'm tired or maybe you didn't copy the question correctly but otherwise it seems like their answer is wrong.
