Question

Suppose that you have 5000$ in your bank account and each month you withdraw 14% of the money left in the account. How long will it take for there to be 1000$ left in the bank account?

Expert Solution
Step 1

I withdraw 14% of the money every month. 

So at the end of every month, there is (1-0.14)=0.86 of the amount, which was there at the starting of the month.

Initial amount = $5000

Let after x months there will be $1000 left in the bank account. 

We can express this using an equation.
