How is gross profit 30% for this question? I've been getting 28% and different percentages for all the products. I previously asked how to calculate profitability on gross percentages. This is for the Company CoCo case study. The responder said that the gross percentage for each chocolate was 30% dark 20% milk and 25% white. I am not sure if they meant hypothetically or actually. What I mean is it OK that I have different gross percentages.
