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

This math topic focuses on calculating the principal amount in various simple interest problems, using given values for interest, rate, and time. It practices deriving the initial amount of money loaned or invested, based on the interest it earns over a specified period at a specified rate, enhancing skills in working with percentages and basic algebraic manipulations within the context of financial mathematics. Each question provides a financial scenario, and multiple-choice answers are offered to determine the principal amount.
