Question

Misty Moon Amphitheater 的每一排有

33

个座位。第

12

排到第

22

排预留给一个青年俱乐部。这个俱乐部一共预留了多少个座位？

Each row of the Misty Moon Amphitheater has

33

seats. Rows

12

through

22

are reserved for a youth club. How many seats are reserved for this club?

297

330

363

396

726

先数从第

12

排到第

22

排一共有多少排，包括两端。

Count how many rows run from

12

through

22

inclusive

将排数乘以

33

。

Multiply the number of rows by

33

第

12

排到第

22

排共有

22 - 12 + 1 = 11

排。

每排有

33

个座位，所以总数为

33 \times 11 = 363

。

所以正确答案是 C。

Rows

12

through

22

inclusive make up

22 - 12 + 1 = 11

rows.

Each row has

33

seats, so the total is

33 \times 11 = 363.

Thus, the correct answer is C.
