Simple Interest

Interest is paid for borrowing money. There are different ways of calculating interest. Simple interest is a fixed percentage of the amount borrowed and is calculated on the original amount. The formula used is I =Prn where I is the interest, P is the amount initially borrowed, r is the rate of interest and n is the number of time periods borrowed for.
