This topic focuses on exponential decay in various applications, specifically with mismatched time units for calculations. It involves rearranging exponential equations to find the time necessary for a substance or fund to decrease to a given value, after undergoing consistent percentage reductions over specified time intervals. Students exercise the skill of manipulating exponential functions to solve real-world oriented problems involving toxins, endowments, and other scenarios where values decrease over time. Each question presents a different scenario, requiring the correct setup and algebraic manipulation of decay formulas to find the time at which particular conditions are met.
