This math topic focuses on solving and rearranging exponential decay equations involving continuous models with mismatched time units for variables like population or concentration. The primary skill practiced is algebraic manipulation of exponential functions to isolate and solve for the initial value, known as the starting value. The problems entail working with decay models for different scenarios, including the decay of radioactive substances and the decline of various populations (e.g., bacteria, whales, birds). Each question provides an equation and asks to solve for the starting value given specific decay parameters and time ratios.
