Answer 1

To determine which statement is correct, we need to calculate the average time spent on homework per day by both Marco and Maribella.

Marco's Homework:

• 3 days: 3.25 hours → average: \( \frac{3.25}{3} \approx 1.0833 \) hours per day
• 9 days: 9.75 hours → average: \( \frac{9.75}{9} \approx 1.0833 \) hours per day
• 12 days: 13.0 hours → average: \( \frac{13.0}{12} \approx 1.0833 \) hours per day
• 30 days: 32.5 hours → average: \( \frac{32.5}{30} \approx 1.0833 \) hours per day

Average for Marco: Marco consistently spends approximately 1.0833 hours per day.

Maribella's Homework:

• 4 days: 4.2 hours → average: \( \frac{4.2}{4} = 1.05 \) hours per day
• 8 days: 8.4 hours → average: \( \frac{8.4}{8} = 1.05 \) hours per day
• 20 days: 21.0 hours → average: \( \frac{21.0}{20} = 1.05 \) hours per day
• 28 days: 29.4 hours → average: \( \frac{29.4}{28} \approx 1.05 \) hours per day

Average for Maribella: Maribella consistently spends 1.05 hours per day.

Comparison:

• Marco's average: \( \approx 1.0833 \) hours per day
• Maribella's average: \( 1.05 \) hours per day

Conclusion: Since Marco spends more time on homework per night (approximately 1.0833 hours) compared to Maribella (1.05 hours), the correct statement is:

Maribella spends less time on homework per night.
