12Computing Simple Interest

Computing simple interest is a great way to quickly figure out whether an investment has value. It’s also a good way to get comfortable with explicitly coding the order of operations in your programs.

Create a program that computes simple interest. Prompt for the principal amount, the rate as a percentage, and the time, and display the amount accrued (principal + interest).

The formula for simple interest is images/_pragprog/svg-0003.png, where P is the principal amount, r is the annual rate of interest, t is the number of years the amount is invested, and A is the amount at the end of the investment.
