Rockham Soccer League 的成员购买袜子和 T 恤。袜子每双 $\$4$ ，每件 T 恤比一双袜子贵 $\$5$ 。每位成员主场比赛需要一双袜子和一件 T 恤，客场比赛也需要一双袜子和一件 T 恤。如果总费用为 $\$2366$ 联盟共有多少名成员？

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?

$77$

$91$

$143$

$182$

$286$

答案：B

解答：

每件 T 恤价格为 $\$4 + \$5 = \$9$ 。

每位成员需要两双袜子和两件 T 恤，费用为 $2 \cdot 4 + 2 \cdot 9 = \$26$ 。

成员数为 $2366 \div 26 = 91$ 。

所以正确答案是 B。

Each T-shirt costs $\$4 + \$5 = \$9.$

Each member needs two pairs of socks and two shirts, costing $2 \cdot 4 + 2 \cdot 9 = \$26.$

The number of members is $2366 \div 26 = 91.$

Thus, the correct answer is B.
