Simple Interest

Simple Interest is the interest calculated on the principal amount only, without compounding. It is calculated using the formula I = PRT, where I is the interest, P is the principal, R is the rate of interest, and T is the time in years.

The formula for calculating Simple Interest is I = PRT.

In the formula I = PRT, 'P' stands for Principal, which is the initial amount of money borrowed or invested.

In the formula I = PRT, 'R' represents the Rate of interest, expressed as a decimal.

In the formula I = PRT, 'T' represents Time, which is the duration for which the money is borrowed or invested, measured in years.

The interest will be $300, calculated as I = 1000 * 0.10 * 3.

To convert a percentage to a decimal, divide the percentage by 100. For example, 8% becomes 0.08.

The rate of interest is 10%, calculated using the formula R = I / (PT) = 400 / (2000 * 2).

The total amount to be paid back is $1800, calculated as Total Amount = Principal + Interest = 1500 + (1500 * 0.05 * 4).

The interest rate is 2.5%, calculated using the formula R = I / (PT) = 60 / (1200 * 2).
