- The following problem is from both the 2003 AMC 12A #2 and 2003 AMC 10A #2, so both problems redirect to this page.
Problem
Members of the Rockham Soccer League buy socks and T-shirts. Socks cost $4 per pair and each T-shirt costs $5 more than a pair of socks. Each member needs one pair of socks and a shirt for home games and another pair of socks and a shirt for away games. If the total cost is $2366, how many members are in the League?
Solution
Since T-shirts cost 
dollars more than a pair of socks, T-shirts cost 
dollars.
Since each member needs 
pairs of socks and T-shirts, the total cost for 
member is 
dollars.
Since 
dollars was the cost for the club, and 
was the cost per member, the number of members in the League is 
.
