This math topic covers problems related to finding the starting values of quantities experiencing exponential decay with discrete time intervals and mismatched time units. It includes scenarios where the decay occurs on a weekly or daily basis due to factors such as dialysis treatments reducing toxin concentration or disbursements depleting a charitable endowment. The skills practiced involve applying exponential decay formulas, with some complexity introduced by converting mismatched time units (days to weeks, daily changes over multiple years) into correct formula applications to solve real-life, time-based decay problems.
