\$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

知识点：钱币比与比例

难度评级：1050

小提示：

一件 T 恤价格为

\$4 + \$5 = \$9

。

A T-shirt costs

\$4 + \$5 = \$9

大提示：

每位成员需要两双袜子和两件 T 恤。

Each member needs two pairs of socks and two shirts

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.
