Final answer:
Corporations are the most dominant in terms of total sales revenues compared to sole proprietorships and partnerships, due to their ability to raise capital through stock sales and their larger overall scale.
Step-by-step explanation:
When comparing sole proprietorships, partnerships, and corporations in terms of total sales revenues, corporations are the most dominant. One of the reasons for this is that corporations can raise significant capital by selling shares to the public, which can lead to expansive growth and higher revenues.
Sole proprietorships, while numerous and easy to start, are often less profitable and generally smaller in scale. Partnerships, common among professionals like doctors and lawyers, can accumulate substantial earnings, but they tend to be less prevalent than corporations in accumulating massive total sales revenue.
Corporations tend to be more formal and legally complex than sole proprietorships or partnerships. They must seek permission to incorporate from national and state governments and can either remain private or go public by issuing stock.
Some large private corporations, such as Cargill and Mars, although not trading publicly, still report tens of billions of dollars in annual sales, showcasing that corporations have a significant impact on total sales revenues in comparison to other business types.
