Interest (Simple) - Rate From Interest, Principle, and Time (Level 2)

This math topic focuses on calculating the simple interest rate given the principal, amount of interest, and time. These problems are part of a broader unit on percents and simple interest. Each question presents unique values for the principal, interest, and time, and requires finding the corresponding interest rate. Students are given multiple choices for each problem to select the correct rate. This practice aims to enhance students' understanding in dealing with monetary concepts and applying mathematical skills to real-world situations like finance and investments.
