Answer:
$6,000
Step-by-step explanation:
If I have not misinterpreted the question, then you only need to subtract to find the answer.
If bank account began with $9,000, then we are taking money away from that $9,000. So we know 9,000 minus a certain amount equals the answer.
The titanium watch cost $3,000. We need to take $3,000 away from the original $9,000 in Tanner's bank account. So, we can set up the equation:
9,000 - 3,000 = ______.
The blank is the answer to your question. When you take away 3,000 from 9,000, you get 6,000. This means that Tanner's final balance is $6,000. That is, unless there is tax involved.
