What I did was since the line y=mx+1 cuts y-axis at 1, therefore for it to have one solution, the gradient had to be equal or steeper then the right arm of the curve y=|2x-3|, which had gradient 2. The gradient cannot be negative because it will cut twice.
you could also have it cut on the second arm of the absolute graph thing second arm

it's 8 years, i did it manually after fucking up as well

7 years gives = 87350 and she needs 87500 so 8 years

fuck i included 1/3 of 33000 shit shit shit is this wrong?
I did something like 1/3(33000n + 1500n) > 87500,
Then its like 11500n > 87500,
n > 7.6,

So it's 8 years.

Dunno if this is legit, but it worked out for me :D

Yeah, I remembered I solved a quadratic for n^2+43n-350=0 and you get n=7 n=-43, discarding the negative you get n=7

That paper was harder than all the previous years by heaps -.- FML.

Anyway, here's the paper since many of you want it. I cleared out some of my writing/working out so i hope you guys don't mind.

Enjoy. :)

If it weren't for the huge amount of working out needed for the stupid little questions, would've done a lot better.
