This topic focuses on solving exponential decay equations to determine the initial quantity from a given remaining amount after a period of consistent percentage decrease. It presents real-world scenarios involving the reduction of toxin concentration and population decline of whales and birds over time. Each problem requires rearranging an exponential formula to solve for the starting concentration or population based on the decay rate and final measurement after a specified time.
