This math topic explores the application of exponential decay functions to solve for time, using scenarios where quantities decrease by a fixed percentage per time period. Problems include calculating the time required for toxins to decrease to specific concentrations following periodic dialysis treatments, determining years for bird or whale population declines, and calculating weeks until a charitable fund dwindles to a certain amount following weekly disbursements. Each scenario requires rearranging an exponential decay equation to solve for time, enhancing skills in logarithmic manipulation and understanding of exponential behaviors in real life contexts.
