    Interested as to how this exam was, because D1 has changed quite a bit in places - were the questions relatively standard?

    I guessed that with the order but it didn't feel enough for 5 marks with the few pages after I just wrote about the order being two times the edges and made up a load of bs to go with it

    If x and y were 25 and 50, wouldn’t that be the maximum? Most of my friends got 25 x and 42 y ://
    I ran out of time so annoyed I didn’t add the z value

    yeah i'm really confused, i worked out x =25 and y=42 but this doesn't work as it was supposed to be that it all adds up to 150 including z, and my values didn't work. so i don't know what went wrong because i used the whole find a minimum and stuff, and found the minimum but it didn't suit what the question asked. so i just hope i get the method marks. :/

    what objective function people used. I subbed in 150-x-y =z into the given one. I think it came out as Cost = 50X + 75Y + 30000

    yeah 25 and 42 give a lower value 34400. I probably solved the wrong lines simultaneously

    Did we know the z value?? I though you just took worked out x and y off 150 at the end (I’m not 100% because I didn’t finish)

    I think so too! But I messed up on the Poisson approximation because I concerted the poisson to the binomial but then forgot to convert that to poisson again ! hopefully not dropped too many marks from that
