[GRLUG] Math Question

[Adam Tauno Williams]

So maybe a bit off topic, but I know we have people here you love to
argue about such things.

I have three types of equipment: X, Y, & Z.
Given $1.00 I know that in a year a single type X will typically consume
14% of that $1, type Y 30%, and type Z 56%.  So if I have x Xs, y Ys,
and z Zs how do I calculate what percentage of the maintenance budget of
N will typically be consumed by type X, Y, and Z?
