Homework Help: Algebra again

  1. Mar 4, 2005 #1
    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...

    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.
