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 opera- tions 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 A = P(1 + rt), 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.
Enter the principal: 1500
Enter the rate of interest: 4.3
Enter the number of years: 4
After 4 years at 4.3%, the investment will be worth $1758.

Prompt for the rate as a percentage (like 15 , not .15 ). Divide the input by 100 in your program.

Ensure that fractions of a cent are rounded up to the next penny.

Ensure that the output is formatted as money.
