This math topic focuses on modeling scenarios of exponential decay with discrete time steps using equations. The problems involve calculating the decay of populations, concentrations, and funds over time, given a constant percentage decline each period. Each problem includes a real-world situation, such as a declining bird or whale population, toxin reduction through dialysis, or the depletion of a charitable endowment, and asks to identify the correct exponential decay equation from multiple choices. This set of problems practices setting up and understanding exponential decay equations in contexts that model decreasing quantities over time.
