The equation H=62+12(a-50) can be used to represent the maount of new hair growth on a Hair Club for men client. find the amount of hair, H, of a a client after 117 applicatons, a.

Not a favourable formula for the Hair Club.

One would have to have at least 50 applications before any growth is obtained, any number less than that would actually cause a decrease of hair. Wow!

I would just sub in a=117
