To determine who spends less time doing homework per night, we need to calculate the average hours spent per day for both Marco and Maribella based on the given data.
### Marco's Homework:
1. **3 Days: 3.25 Hours**
Average per day = 3.25 hours / 3 days = 1.0833 hours/day
2. **9 Days: 9.75 Hours**
Average per day = 9.75 hours / 9 days = 1.0833 hours/day
3. **12 Days: 13.0 Hours**
Average per day = 13.0 hours / 12 days = 1.0833 hours/day
4. **30 Days: 32.5 Hours**
Average per day = 32.5 hours / 30 days = 1.0833 hours/day
### Maribella's Homework:
1. **4 Days: 4.2 Hours**
Average per day = 4.2 hours / 4 days = 1.05 hours/day
2. **8 Days: 8.4 Hours**
Average per day = 8.4 hours / 8 days = 1.05 hours/day
3. **20 Days: 21.0 Hours**
Average per day = 21.0 hours / 20 days = 1.05 hours/day
4. **28 Days: 29.4 Hours**
Average per day = 29.4 hours / 28 days = 1.05 hours/day
### Comparison:
- **Marco's average**: 1.0833 hours/day
- **Maribella's average**: 1.05 hours/day
From the calculations, we can see that Marco spends more time on homework per day compared to Maribella.
### Conclusion:
The correct statement is: **Maribella spends less time on homework per night.**
