This question is a little ambiguously worded, however I assume the answer would simply be:
$500 - $112 - $28 = the amount he has left.

To convert a mixed fraction into an improper fraction:
To solve for the given problem above:
Let x be the number of boxes left after 3 hours
3 * ½ X = 24
3/2 X = 24
X = 24 * 2/3
X = 16
The correct answer is 16.
