This is a Combo Pack of two of my lessons...
Simple Interest vs Compound Interest: This lesson compares simple interest to interest that is compounded annually. After computing compound interest in multiple steps, students discover a future value formula for compound interest.
Appreciation and Depreciation: Future value of investments are used in real life context for exponential growth and decay problems. Contains group work exercises.
In both lessons, functions for computing simple interest and compound interest over time are developed and related to their graphs.
