Answer: 12
Explanation:
Since Duane has 30 pairs of socks in a drawer and he has 6 matched pairs and the rest are of the socks are mismatched, the number if mismatched socks will be:
= 30 - 6
= 24 mismatched socks
Since he packed 1/2 of his mismatched pairs in his duffle bag for a week at summer camp, therefore, the number of socks he packed will be:
= 1/2 × 24
= 12
Therefore, he packed 12 socks for summer camp.
