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 touch on specialized scientific concepts, like radioactive decay, but don't require prior scientific knowledge.
- The basic approach involves taking the given starting value and applying the specified multiplier or divider over the stated time intervals to find the final amount.
- Step-by-step calculation through each given time interval is crucial to solving these problems.
- Examples include calculating the remaining mass of a radioactive isotope after a series of half-life periods and determining the size of a bacteria population after several growth intervals.
