Simple Interest Concepts and Calculations

The video tutorial explains how to calculate simple interest using the formula I = P * R * T. It demonstrates how to solve for the interest rate by rearranging the formula to R = I / (P * T). An example is provided where a principal of $10,000 accrues $3,625 in interest over five years, resulting in a 7.25% interest rate. The video also covers converting a decimal to a percentage and concludes with additional examples.
