Based on the given tables, the correct statement is that Marco spends less time on homework per night.
Based on the information provided, the correct statement is:
Maribella spends less time on homework per night.
To determine who spends less time on homework per night, we can calculate the average number of hours per day for each person. The average number of hours per day can be found by dividing the total number of hours by the total number of days.
For Marco:
Total number of hours = 3.25 + 9.75 + 13 + 32.5 = 58.5
Total number of days = 3 + 9 + 12 + 30 = 54
Average number of hours per day = 58.5 / 54 = 1.08 hours
For Maribella:
Total number of hours = 4.2 + 8.4 + 21 + 29.4 = 63
Total number of days = 4 + 8 + 20 + 28 = 60
Average number of hours per day = 63 / 60 = 1.05 hours
Comparing the average number of hours per day, we can see that Marco spends less time on homework per night. Therefore, the correct statement is:
Marco spends less time on homework per night.
