Alright, ALMOST done this assignment...
i just need to solve this problem.
The limit as n goes to infinity = 1+r (pa(n) + 0.9 pi(n) + 1.1 ps(n)) = 1
(pa(n) +pi(n) + ps(n))

I need to solve for r...
Cheers

I have no idea what you mean! What are pa(n), pi(n), ps(n)?
Was that last (pa(n)+ pi(n)+ ps(n)) intended to be a denominator? What are those "=" supposed to mean? Normally, you find the limit of an expression, not an equation.

I think those "a","i","s" are subscripts.But i have no idea where they come from...
