How can you calculate simple interest principle rate and time? - Answers

To calculate simple interest, you can use the formula: ( I = P \times r \times t ), where ( I ) is the interest earned, ( P ) is the principal amount, ( r ) is the annual interest rate (expressed as a decimal), and ( t ) is the time in years. To find any of the variables, you can rearrange the formula accordingly: ( P = \frac{I}{r \times t} ), ( r = \frac{I}{P \times t} ), or ( t = \frac{I}{P \times r} ). Ensure that the time period matches the interest rate's time frame for accurate calculations.
