Use exponent properties to interpret exponential expressions, including percent growth and decay.
Find the cumulative percent change from an exponential multiplier over several periods
Problem
Find the cumulative percent change for multiplier \(1.1\) over \(2~\text{periods}\).
Big Picture
What this problem is really about
Repeated percent changes compound through multipliers rather than by adding the period rates. We’ll raise the one-period factor to the number of periods, subtract the original whole from the cumulative factor, and convert the remaining net change to percent.
