    y is 50% bigger therefore y=3/2x, its not x which is 50% bigger

    No

    So how hard was that D1 in all seriousness? I found it much harder - certainly time wise - than practice exams.

    I got that as well tbh ... don't know whether it's right or wrong but that was my logic when reading the question.

    Yes, y is 50% bigger

    Saying 1.5x+y is the same as saying that x is bigger than y. Just look at the coefficient of both x and y. 1.5>1 and as you said before y is 50% bigger, therefore it should be x+1.5y

    It was just as hard as last years I think and last year was 58 for an A but to be honest I wouldn't be surprised if an A was between 58-62

    That's not correct logic.

    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.

    C = x + 1.5y

    C = 4 + 1.5(7) = 14.5 units

    (you know this is correct because you can work it out yourself doing 4 * 1 + 7 * 1.5 = 14.5)

    Standard difficulty, it could have been worse. Hoping for a similar grade boundary as last year although I wouldn't be surprised if 59-60 is an A
