Understanding Percent Change and Growth

The video tutorial covers solving percent change and percent error problems. It begins with an introduction to the concepts and equations related to percent change. The instructor then walks through a quiz problem to determine the greatest year of student growth using percent calculations. Following this, an example is provided to calculate percent error using a bolt's measurement. The video concludes with a summary of key equations and a reminder to write them down for future reference.
