The idea here is to see how many years it will take a bank account to grow to at least a given value, assuming a fixed annual interest. Write a program savings.py. Prompt the user for three numbers: an initial balance, the annual percentage for interest as a decimal, like .04 for 4%, and the final balance desired.
All the monetary amounts that you print should be rounded to exactly two decimal places. Start by printing the initial balance this way. For example, if the initial balance was entered as 123.5, it should be reprinted by your program as 123.50. Also print the balance each year until the desired amount is reached or passed. The first balance at or past the target should be the last one printed.
The math: The amount next year is the amount now times (1 + interest fraction), so if I have $500 now and the interest rate is .04, I have $500*(1.04) = $520 after one year and after two years I have, $520*(1.04) = $540.80....
For example, if I respond to the prompts, and enter into the program a $500 starting balance, .04 interest rate and a target of $550, the program prints:
500.00
520.00
540.80
562.43
