Applying radioactive decay to determine the percent left of compound

The video tutorial explains growth and decay models, focusing on the half-life of radioactive radium. It provides a step-by-step guide to solving for the decay rate and calculating the percentage of radium remaining after 100 years. The tutorial uses the formula Y = A * e^(RT) and demonstrates how to apply logarithms to solve for the decay rate. The conclusion shows that 96% of radium remains after 100 years, given its half-life of 1620 years.
