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)
Wait so what are you trying to say the answer is
2. For the linear programming I forgot to plot the first point urghhhh
Therefore my x and y value from simultaneous equations was wrong
I got the objective function
I then used these values to put them in the objective function
Overall how many marks am I likely to get

Wait so what are you trying to say the answer is
C = x + 1.5y
4. mark scheme anywhere??? cant find it
5. the question said the capacity of y is 50% greater than that of x hence the total capacity will be C = x + ( y +0.5X) giving you C = 1.5x +y
6. Who was the paper pls
7. Who else thought it was bun pips?
8. Anyone else get this for the matching answer

9. That paper was grim oml worst way to end exams possible

Relax, breath take it easy hear yourself . lets forget the 50% it said y>x so why would you have 1.5x when the container of y is greater than x

Who was the paper pls
Technically, I have it. But I ain't sharing it just yet.
12. Is there an unofficial mark scheme anywhere?

I beg you, please, or atleast you can send it to me.

You're saying y = y + 0.5x ...

X holds 10 units. Y holds 50% more = 15 units. It's x + 1.5y.

Lol nice, but I also put 'failure for D1' as one of them...

Im a million percent sure
Prim= 80
Optimal Vertex = 11,4
Total Cost = £480
Was it not 9,5 and the cost £505?

V was between 10 and 11 for X, and 4 and 5 for Y
18. 135, for the final output right?

Would P=cx+1.5cy get the mark where c is the capacity?

V was between 10 and 11 for X, and 4 and 5 for Y
I'm not fully certain, but don't these values give the optimal number and fit within the enclosed region?
