Filled values:

Grade | Pets | No Pets | Total
6th grade | 29 | 20 | 49
7th grade | 21 | 20 | 41
8th grade | 11 | 34 | 45
Total | 61 | 74 | 135

Calculations:
- 6th pets = 49 − 20 = 29
- 7th pets = 41 − 20 = 21
- 8th total = 11 + 34 = 45
- Column totals: Pets 29+21+11 = 61; No Pets 20+20+34 = 74; Grand total = 135
