To answer the question, we need to compare the number of hours of homework done per night by Marco and Maribella.
Looking at the tables, we can see that Marco's homework time ranges from 3.25 to 32.5 hours for different periods. Maribella's homework time ranges from 4.2 to 29.4 hours for different periods.
By comparing these ranges, we can conclude that Marco spends less time on homework per night compared to Maribella. Therefore, the correct statement is:
Marco spends less time on homework per night.
To determine who spends less time on homework per night, we can compare the average number of hours of homework done by Marco and Maribella for the different periods of time.
For Marco:
Average hours of homework per night = (Total hours of homework) / (Number of days)
For Maribella:
Average hours of homework per night = (Total hours of homework) / (Number of days)
Let's calculate the average hours of homework per night for Marco and Maribella:
For Marco:
Average hours of homework per night = (3.25 + 9.75 + 13.0 + 32.5) / (3 + 9 + 12 + 30)
Average hours of homework per night = 58.5 / 54
Average hours of homework per night ≈ 1.083 hours
For Maribella:
Average hours of homework per night = (4.2 + 8.4 + 21.0 + 29.4) / (4 + 8 + 20 + 28)
Average hours of homework per night = 63.0 / 60
Average hours of homework per night ≈ 1.05 hours
Comparing the averages, we can see that Maribella spends less time on homework per night.
Therefore, the correct statement is: Maribella spends less time on homework per night.
