    How did everyone find it? I forgot a few things, but I'm hoping for a low/mid A. Thought it was a pretty standard paper, but I was disappointed to not see an algorithm question though!

    For Q8b, doesn't x=21 and y=10 give P=£515? I'm sure the equation was P=15x+20y

    I got profit 520? I used x=24 and y=8.

    My lower = upper bound, 62 (the other upper bound I had was 67).

    Prim's matrix was 36.

    For Chinese postman I had 22, 32 and 42.
    Yeah i got 24 and 8

    it sure does... i typod it. in the exam i put £515

    i dont know how people are getting x=24 y=8 its not the same objective line.

    objective line was y=-(3/4)x
