    Eyy Newton Raphson Jam your hype, it was
    C= 2x + 3y ( x + 1.5y )
    Pretty sure the gradient was -1.5, so I think she's right

    Guys I am 100% sure the objective line was x+1.5y. There was a basically identical question in a previous paper & I worked it all out today at the end and it was definitely x + 1.5y

    maximise 1.5x+y obviously it clearly said y is 50% larger than x, therefore, you multiply x by 1,5.
    Please see my explanation I showed someone earlier

    Plug in values if you don't believe me.

    Let's say a standard container holds 1 unit of storage. Therefore a deluxe container holds 1.5 units, yes? (since deluxe is 150% of standard)

    Let's say we bought 4 standard containers and 7 deluxe containers.

    So firstly let's just forget about any objective function and work the capacity ourselves. 4 lots of 1 storage + 7 lots of 1.5 storage = 14.5 units of storage. Agreed? Good.

    Let's see if this one works...

    C = x + 1.5y

    C = 4 + 1.5(7) = 14.5 units

    It does

    Let's see if this one works

    C = 1.5x + y

    C = 1.5(4) + 7 = 13

    It doesn't work.

    It was 1.5y - people aren't thinking about this properly and I'm expecting the examiner's report to be savage :lol:

    Wait who is 'she' ? And the gradient I thought was -1/1.5=-2/3, ain't it ?

    In the content of a 2 unknown equation( of x and y) y=1.5x makes sense. However, it's not true for those types of questions. ( there are many examples of u look at the past papers, I used to get them wrong) having said that I might be wrong .... 😅☝️
    Yes however it was an objective function. You cannot, through simple thinking and logic, have maximise c = y = 1.5x. It is the TOTAL amount. So you have C = x + 1.5y

    I'm not quite sure what you're saying here.

    If it said something like "the storage of a deluxe box is 50% more than that of a standard box (x) . Write down the storage of a deluxe box in terms of the storage of a standard box"

    Then yes you'd say y = 1.5x

    But it's not what it's asking here. That's what too many people are confusing themselves with.

    I predict two marks lower per grade for this years paper.

    I thought many people didn't finish the paper properly( my self left the scheduling like a boss! Lol) therefore, I'd say yes. Say it's top 10% for 100 ums. I don't think any more than 15% managed to finish the paper. (Thou it's based on TSR where ppl comment when they haven't done that good at the exam) #thoughts

    I put y + 1.5x .. not gunna lie ... because I was thinking in the way that guy was as well... noticed there was a question similar to that in a past paper .. and yes you are right ... so I'll just lock myself in a toilet and just **** the rest of my life ;-P
