In this lesson, students learn how to use the math/solver and the simple interest equation on a graphing calculator to find either the principal, maturity value, time period, or the interest rate of loans and savings using the simple interest model. The lesson provides several solution techniques, such as the quadratic formula, using a table of values, and solver, to help solve equations. The graphing solution technique is highlighted as the most powerful and efficient. Students are encouraged to learn how to properly get a window around the graph to optimize their solving capabilities.
