Simple interest is money you can earn by initially investing some money (the principal). It can be calculated by the equation expressed as: I = Prt where P is the Principal amount of money to be invested at an Interest Rate R% per period for t Number of Time Periods. We calculate as follows: 225 = 500(.075)t t = 6 years
