Did you have a question?

you want how many units sold to make target profits?
x units = total $.
1 units = some $.
total money divided by some money = how many portions you need.

first you decide what your target profits are.
then you decide how much profit per unit you can make.
then you divide the total profit you want, by how much profit you get for one unit, and
see how many units you have to sell.


then you divide the target profits
