To find out who spends less time on homework per night, we need to calculate the average hours of homework done per day for both Marco and Maribella.
Marco’s Homework:
- For 3 days: 3.25 hours / 3 days = 1.08 hours per day
- For 9 days: 9.75 hours / 9 days = 1.08 hours per day
- For 12 days: 13.0 hours / 12 days ≈ 1.08 hours per day
- For 30 days: 32.5 hours / 30 days ≈ 1.08 hours per day
Average for Marco: Marco consistently spends about 1.08 hours each day on homework.
Maribella’s Homework:
- For 4 days: 4.2 hours / 4 days = 1.05 hours per day
- For 8 days: 8.4 hours / 8 days = 1.05 hours per day
- For 20 days: 21.0 hours / 20 days = 1.05 hours per day
- For 28 days: 29.4 hours / 28 days = 1.05 hours per day
Average for Maribella: Maribella also consistently spends about 1.05 hours each day on homework.
Comparison:
- Marco spends approximately 1.08 hours per night on homework.
- Maribella spends approximately 1.05 hours per night on homework.
Conclusion: Marco spends more time on homework per night than Maribella. Therefore, the correct statement is:
Marco spends less time on homework per night. - This statement is false.
The correct statement would be: Maribella spends less time on homework per night.
