Let’s break it down:

- The month starts on a Saturday. So, Day 1 is Saturday.

- In 30 days, let’s see how many Sundays we’ve got. The Sundays fall on Day 2, 9, 16, 23, and 30. That’s 5 Sundays.

- That means the other 25 days are not Sunday.

- Sundays: 5 × 330 = 1650 visitors.

- Other days: 25 × 240 = 6000 visitors.

- Total visitors in 30 days = 1650 + 6000 = 7650.

- Average per day = 7650 ÷ 30 = 255.

Option 2: 255 is the right answer.
