To solve this problem, we need to fill in the missing values in the two-way table based on the data provided. Let's analyze what we have:

  1. For Friday, the total number of students (7th + 8th graders) is given as 52.
  2. On Saturday, the number of 8th graders is 35, but we need to find the number of 7th graders attending that day.

From the table:

  • 7th graders attendance on Friday: 24
  • 8th graders attendance on Friday: Unknown
  • Total Friday attendance: 52

Let’s use this information to calculate the number of 8th graders attending on Friday:

Number of 8th graders on Friday = Total on Friday - Number of 7th graders on Friday = 52 - 24 = 28

Now we know:

  • 8th graders attendance on Friday: 28

Next, for Saturday, we know:

  • Total 8th graders on Saturday: 35
  • 7th graders attendance on Saturday: Unknown

We also need to calculate the total number of each grade across both days.

The total number of 8th graders (both days) can now be calculated.

Total 8th graders = 8th graders on Friday + 8th graders on Saturday = 28 + 35 = 63

Now, looking at the response options given, the correct total number of 8th graders is:

63
