For Marco:
- For 3 days, Marco did 3.25 hours of homework, which averages to 3.25/3 = 1.08 hours per night.
- For 9 days, Marco did 9.75 hours of homework, which averages to 9.75/9 ≈ 1.08 hours per night.
- For 12 days, Marco did 13.0 hours of homework, which averages to 13.0/12 ≈ 1.08 hours per night.
- For 30 days, Marco did 32.5 hours of homework, which averages to 32.5/30 ≈ 1.08 hours per night.
For Maribella:
- For 4 days, Maribella did 4.2 hours of homework, which averages to 4.2/4 = 1.05 hours per night.
- For 8 days, Maribella did 8.4 hours of homework, which averages to 8.4/8 = 1.05 hours per night.
- For 20 days, Maribella did 21.0 hours of homework, which averages to 21.0/20 = 1.05 hours per night.
- For 28 days, Maribella did 29.4 hours of homework, which averages to 29.4/28 ≈ 1.05 hours per night.
By comparing the averages, we can see that both Marco and Maribella spend almost the same amount of time doing their homework per night, approximately 1.08 hours for Marco and approximately 1.05 hours for Maribella. Therefore, the correct statement is:
