Interest (Simple) - Time from Interest, Principle, and Rate (Level 3)

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

Level 3

This topic focuses on calculating the duration of time required to accumulate a given amount of simple interest, given the principal amount and the rate of interest. The problems require the application of the formula for simple interest to deduce the time period. This involves manipulating the basic simple interest equation, $ I = P \times R \times T $, to solve for $ T $ (time), where $ I $ is the interest earned, $ P $ is the principal amount, and $ R $ is the rate of interest expressed as a decimal. Each question presents different values for $ P $, $ I $, and $ R $, and the learners select the correct $ T $ from multiple choices.
