Exponential Growth and Decay - Problem 5 193 views

Some items decrease in value over time, and we can use exponential modeling to predict how much they'll be worth after a certain amount of time or how long until it reaches a certain value. Depending on where the unknown quantity lies in the formula set up, you may need to use the change of base formula to evaluate a log. Remember that since the value is decreasing, we'll use 1 minus a rate in the parentheses, and be sure to write the rate as a decimal.
