Besides that, the numbers can vary greatly depending on many factors, so our goal here is just to provide a few benchmarks that give some sense of the magnitude of potential improvements. Recall the basic equation for enterprise profit: where Q is quantity sold, P is price, V denotes variable costs, and C denotes fixed costs.
