**Steve**, Wednesday, June 6, 2012 at 12:25pmSay he bought n shares for $x of 1st stock.

nx = 28000

(n+6)(x-6) = 28000

nx+6x-6n-36 = 28000

we know nx=28000, so

6x-6n = 36

x-n=6

now, n=28000/x, so

x - 28000/x = 6

x^2 - 6x - 28000 = 0

x = 3±√28009

x = 170.36

164.36*170.36 = 28000.37

170.36*164.36 = 28000.37

Odd that the solution was not integers
