Melanie has $64 in her checking account. she writes a check for $75. What is Melanie's checking account balance after writing the check?

Question

I don't know how to do this question 

Answer 1

If she writes a check for $75, she is essentially withdrawing, or subtracting $75 from her account. However, she is attempting to take out more than she has in the account. This will result in a negative balance. 

 

64 - 75 = 64 + (-75) = -11 dollars
