I need to know the name and formula for this problem.
I have widgets which have a certain lube content to them. We currently are selling the widgets for 3.00 each. The lube costs .50 cents for each widget, but we are considering a change in the lube content from the current state of 1 oz. We currently are making sales of 1000 widgets per year. I want to know how many more widgets we would have to sell in order to justify a given increase in the lube content of a widget. I am not asking how many more we would sell if we increased the lube content or what the revenue would actually be. I am merely asking what the number of additional widgets sold must be in order to justify a given lube content increase.
Price of widgets is constant.
What is the name of the formula I am seeking? What is the formula I am seeking? What is the answer?
