Based on the data, what was the approximate average number of visitors per hour during the weekend (Saturday and Sunday…

Correct answer: B. 16

To find the average number of visitors per hour on the weekend, first find the total number of visitors on Saturday and Sunday. According to the table, this is 150 + 100 = 250 visitors. Next, find the total number of hours the library was open during the weekend. The library is open for 8 hours each day, so over 2 days (Saturday and Sunday), it was open for 2 * 8 = 16 hours. Finally, divide the total number of weekend visitors by the total number of weekend hours: 250 visitors / 16 hours = 15.625 visitors per hour. The question asks for the approximate average number of visitors. The value 15.625 is closest to 16. A is incorrect. This is the approximate average number of visitors per hour for the entire week (650 visitors / 56 hours ≈ 11.6). C is incorrect. This is the result of dividing the total weekend visitors by the hours for a single day (250 / 8 ≈ 31.25). D is incorrect. This is the average number of visitors per day on the weekend, not per hour (250 / 2 = 125).
