Question

Your checking account is overdrawn by $50. You write a check for $20. What is the balance in your account?

Answer 1

"overdrawn by $50"

Your checking account balance would then be $-50

And now you are writing a check of $20. That is another 20 out of your account

Your balance will be -50 - 20 = -70

Your balance is $-70

Answer 2

Your current balance is -50

You write a check for 20$

You will now have -50 - 20 = $-70

Hope that helps :)
