Answer:
$240 - $400
Step-by-step explanation:
$320 is Jason's current balance. By saying that this amount can vary by as much as $80, it suggests that he can have $80 less than his current balance, which would be $240, or he can have $80 more than his current balance, which would be $400. This answer can be written as a range since he can have any amount between these two numbers, but his amount just can't be an $80+ difference from his initial balance. The final answer is $240 - $400.
