Solving One-Variable Equations with Percents

OverviewThis set of tutorials provides 42 examples of solving one-variable equations that involve percents. They include these three main types of equations: •Finding the percent of a number (Examples 1-12)•Finding the percent a is of b (Examples 13-33)•Finding the solution to "a is b% of what number?” (Examples 34-42)
