If we know a rate of increase in a product's value (or growth in a population, etc,) we can write a growth model and use it to make predictions about expected values. Be careful with the units (here, time is done in decades) and be prepared to use the change of base formula if you're solving for a variable that is in the exponent. Lastly, we provide an overview of how to use a TI graphing calculator to determine expected value graphically.
