TSR was the cause for quite literally doing nothing in terms of school work and I thought this would have affected my exams (considering I had done no homework in any of my subjects) and I need three a for Oxford. Considering how my exams have recently gone though I found that you can quite literally learn whole modules in one or three days - subject specific - ergo TSR time.
Lol fair enough.

This is the same person ...
lmao!
3. Prettier rep though.

lmao!
Anymore wall challenges?
5. how about something simple, criticise the logical paradox in the statement:
"This statement is false"

lol dean you made a new accout because your rep was low
6. Quickie.

Sir Gustaff is happy when smoking ciggareetes and drinking wine. So happy his happyness is proprtional to the square of the number of bottels of wine he has in one day multiplied by the packets of ciggarettes he has in one day. A bottle of wine costs 3 pounds, ciggarettes cost 2 pound. He has an allowance of 100 pounds. What amount of alcohol and ciggarettes should Gustaff acquire to achive greatest happyness?

is this from a BMO-2?

correct

correct
out of curiosity, do you actually have a solution to the problem?

I do

I know I'm being hick here, but why doesn't the solution set
Oh. Yeah I made that mistake at the first time I read it.

(x,y) are such that - distinct.

a hint by any chance?

It would considereably give the game away as the hint is the solution.

Why wlog can you assume something about (x,y) ?

assume y > x

y = kx

Let y = kx = It is clear that for some n. You can take it that so x must be and therefore

nice. i was at a point of
i didnt really think to let the fraction equal one
