Simple interest is calculated by the product of the principal, number of years, and interest (as a percentage, so either a decimal between 0 and 1). Write code to calculate the simple interest on a principal amount of $10,000 for a duration of 5 years with the rate of interest equal to 12.5%. You don't have to get the values as input from the user. (Hint: Simple, not compound interest. Don't make the formula more complicated than it is; just use the one given.)
