This math topic focuses on solving for time in exponential decay functions, using equations of the form \(P = P_0 \times (1 - r)^t\), where \(P\) represents the final population or amount, \(P_0\) is the initial population or amount, \(r\) is the rate of decay, and \(t\) is the time. Problems include scenarios involving declines in bird and whale populations, the balance of a charitable endowment with monthly disbursements, and the decline in toxin concentrations with dialysis treatments. Students are provided equations and asked to solve for the variable \(t\) to determine the time it would take to reach a given status.
