To determine who spends less time doing their homework, we need to compare the number of hours each person spends per night.
Looking at the tables, we can see that Marco's hours of homework increase consistently with the number of days, while Maribella's hours seem to vary.
Comparing the lowest number of days for each person, Marco did 3.25 hours in 3 days, which is approximately 1.08 hours per night. Maribella did 4.2 hours in 4 days, which is approximately 1.05 hours per night.
While the difference is small, it can be concluded that Maribella spends slightly less time on homework per night compared to Marco.
Therefore, the correct statement is: Maribella spends less time on homework per night.
To answer the question, we need to compare the number of hours Marco and Maribella spend on homework per night. Let's calculate the time spent per night for both Marco and Maribella.
For Marco:
- For 3 days, Marco spends 3.25 hours, so per night he spends 3.25/3 = 1.08 hours.
- For 9 days, Marco spends 9.75 hours, so per night he spends 9.75/9 = 1.08 hours.
- For 12 days, Marco spends 13.0 hours, so per night he spends 13.0/12 = 1.08 hours.
- For 30 days, Marco spends 32.5 hours, so per night he spends 32.5/30 = 1.08 hours.
For Maribella:
- For 4 days, Maribella spends 4.2 hours, so per night she spends 4.2/4 = 1.05 hours.
- For 8 days, Maribella spends 8.4 hours, so per night she spends 8.4/8 = 1.05 hours.
- For 20 days, Maribella spends 21.0 hours, so per night she spends 21.0/20 = 1.05 hours.
- For 28 days, Maribella spends 29.4 hours, so per night she spends 29.4/28 = 1.05 hours.
From the calculations, it can be observed that both Marco and Maribella spend approximately 1.08 hours and 1.05 hours, respectively, on homework per night. Since Maribella spends less time on homework per night, the correct statement is: "Maribella spends less time on homework per night."
