If I have two products. Those products are shirts and shoes. Please see the image.
If I want to calculate the net cost then do I add the all the costs for the shirts for every year, which will give me 60 dollars or do I add it by product by year, so for year 1 (shirts and shoes), it will be 50 dollars. I am confused, when it says find net cost. Similarly, I can do net sales. But, then what about net revenue?
