What is the question?

Maybe, how many fee's worth of credit does aubryn have in the account? This would correspond to how many months this account will last.




Better to close the account or the bank will take the whole credit away, the $75, in 6 months.

Let amount of months the balance of $75 will last be x, and amount after x months, A(x).

Inequality: .

Solving this inequality results in x being 6. This means that the $75 balance will only last 6 months 

before the account "runs dry."

You can do the check!!
