Imagine that you would like to open a small ice-cream shop, and know that up-front start-up costs are 50,000 pounds. You also know that every year the business will generate about 20,000 pounds in profits. How would you decide whether your business idea is financially viable?
是从“每年收到的cash flow…… 然后大概几年之后cover掉前期的start up costs”这个角度回答吗
