<span><u><em>Answer:</em></u>
Joe needs 6 more hot dog buns.
<u><em>Explanation:</em></u>
Since Joe's starting amount of hot dogs is 18, we know he will need that many buns.
Since he currently has 12, we can subtract that number from the total amount he needs.
Amount he need - Amount he had = Amount more he needs to buy.
18 - 12 = Amount more he needs to buy.
6 = Amount more he needs to buy.</span>
