Write a script file that will compute the growth in a savings account at the end of every year for n-years. The script should prompt the user to input:
- ‘the initial account balance: ’
- ‘the annual interest rate: ’
- ‘the investment duration in years: ’
Use the formula n B= B (1+r) 0 &xf0d7; , where 0 B is the initial balance, r is the annual interest rate as a fraction, n is the number of years, B is the future value of the investment.
The script should display a 2-dimensional array with n-rows and two columns: The first column should display the years from 0 to n. The second column should display the account balance at the end of each corresponding year.
Test your program with $100 as the input for the initial balance; and, 6.5% as the input interest rate. The output should look like this:
0.0000 100.0000
1.0000 106.5000
2.0000 113.4225
3.0000 120.7950
4.0000 128.6466
5.0000 137.0087

Your formula is not understandable. Characters appear to be missing
The formula also involved the character with unicode code point U+F0D7 which is in the Private Use range and so might mean anything depending on which program is creating the graphics. When I reformatted your question, I represented the character as &xf0d7; which is one of the HTML representations for it.
