Batman buys a combine harvester for £1500 from Joel and Ellie.
On his first year he grows 258 mars bars and sells them for 52p each.
Each year his stock raises by 8% and his prices raise by 4%.
Each year he pays 7% tax.
Every 4 years Cadbury's sue him £43.
Every 7 years there is a zombie Apocalypse and he has to use half of his stock as weapons. How long until he starts making a profit?

pain in the wosits ... I think your lecturer/teacher had too much fun in 1969

A formula is easy until you get to the Apocalypse

P = -1500+ 258x0.52x(1.08x1.04)nx0.93 -43n/4 - (apocalypse every 7 years)

(I got a headache I have been doing maths for the last 9 hours and brain is gone ...)
