How Do You Solve a Word Problem with Exponential Decay?

How Do You Solve a Word Problem with Exponential Decay?

Note:

If something decreases in value at a constant rate, you may have exponential decay on your hands. In this tutorial, learn how to turn a word problem into an exponential decay function. Then, solve the function and get the answer!
