Answer to Question 1
A business is any organization or activity that provides goods and services in an effort to earn a profit. Profit is the financial reward that comes from starting and running a business. More specifically, profit is the money that a business earns in sales (or revenue), minus expenses such as the cost of goods and the cost of salaries. But clearly, not every business earns a profit all the time. When a business brings in less money than it needs to cover expenses, it incurs a loss. If you launch a music label, for instance, you'll need to pay your artists, lease a studio, and purchase equipment, among other expenses. If your label generates hits, you'll earn more than enough to cover all your expenses and make yourself rich. But a series of duds could leave you holding the bag.
