Toilet roll. All our lifes we've taken it for granted. But the grim realisation faced by a student, is that
mammie ain't around to buy it anymore. The dilema most students have is whether to trade quality
in for quantity. Do we spend more for less andrex, and continue our double quilted lifestyle?? Or do
we spend less, and get a mountain of recycled Iranian sandpaper in the pound shop.

We asked renowned scientist 'Professor Herman R Swipe' to investgate for us!!
"Hence I has created the following algorithm to solve it"
"Vell, Vat ve have here is a qeurstion bout ze eggistensial variables wif ze universial quanifiers being ze toilet paper and ze buttocks"
"If we eggstrapolate further, it iz clear dat ven ve buy ze good toilet roll, we get more satisfaction,less iratation, but spend ze lot more money, Ze risk of common arze related dizzfunctions is also reduced"
Where:
X is the cost of the bog roll
"On ze other hand, if ze student is to buy ze cheaper sandzypaper brand of bogroll, whislt ze vill save money, they run a high risk of iritating ze bum. Zis poses a zerious problem in deciding vot is best."
Y is the quantity contained in the pack
Z is the % desire to go to the pub instead.
