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

This is what I did:

OL gradient is -3/4 (so my y was 7.5 and my x was 10).

Furthest point was the intercept of x + y ≤ 32 and 2x + 3y ≤ 72 (iirc), used simultaneous equation and got x = 24 and y = 8.

P = 15(24) + 20(8) = £520

How was it 6 for 2bii,
I got 15, did it not ask for max number of comparisons?
Fs I forgot to plot the 2x + 3y <72 line, how many marks will I drop? Was the max point on that line??


Posted from TSR Mobile
I got 48 for the first prims with 6 points (P, Q, R, S, T, U)
for the 7b prims I got 74
7c I got 67
can someone confirm these?
Right- grade boundary predictions. I think the grade boundaries will be higher than 2015/2014! But of a blow after core 3!

Ahh okay, and yeah I don't get it either, I'm pretty sure it's £515

I got 6, I think the question asked for the max number of comparisons in the 6th pass

Yes it did but only for the 6th pass, so the 6 and 7th element are compared then shuttles down the list comparing with the other 5

I reckon quite high. Between 62 and 64 for an A.
