I am having and issue with a RNF formula. I know how to calculate it at full capacity but I do not know how to calculate it at 70% capacity. Here is my work so far at full capacity: 5,582,000/9,800,000(1,960,000) - 3,290,000/9,800,000(1,960,000) - 4.11%(11,760,000)(1 - 0.40) = 160,798 at full capacity My question is, how do I calculate that at 70%
