4. Output:
What is your account's starting balance? 500
What is your an annual interest rate?
1.5
How much were you paid this month? 1000
We will deposit your pay into your account.
Your current balance is 1500.00
How much would you like to withdraw? 900
This month you have earned 0.75 in interest.
Now your balance is 600.75
