Calculating Interest

Students explore the concept that when money is borrowed, people pay to use it because someone else is losing an opportunity to use it while they have it. What you pay to use the money is called interest. The rate of interest is a percent. The money you borrow is called the principal. Simple interest is paid only on the principal.
