Summary

The content focuses on solving growth and decay word problems, a rare but potential question type on the GMAT exam, emphasizing that all necessary mathematical information will be provided within the question.

- Growth and decay problems involve populations or samples increasing or decreasing over time.
- These problems may reference scientific concepts like radioactive decay but don't require prior scientific knowledge.
- The basic approach involves calculating changes step by step over given time intervals using a starting value and a specified multiplier or divisor.
- Examples include calculating the remaining mass of a decaying radioactive isotope and the growth of a bacteria population over time.
- Key strategy: Take the problem step by step, using the time interval and multiplier/divisor provided to reach the final amount.
