The author uses compare-and-contrast to explain a for-profit business and a nonprofit organization. Both a for-profit business and a nonprofit organization have workers, budgets, and goals. Similarly, both a for-profit business and a nonprofit organization must plan how to use money wisely. Because the text switches between similarities and differences, signal words like "both" and "however" help the reader follow along. However, a for-profit business aims to earn money for owners or shareholders, while a nonprofit organization aims to serve a mission and reinvest money into its work. Another difference is that a for-profit business earns money mainly by selling products or services, but a nonprofit organization often relies on donations and grants. Noticing these details shows how the paragraph is organized.
