Based on the given tables, we can determine the number of hours each person spends on homework per day.
For Marco:
- 3 days of homework = 3.25 hours/day
- 9 days of homework = 9.75 hours/day
- 12 days of homework = 13.0 hours/day
- 30 days of homework = 32.5 hours/day
For Maribella:
- 4 days of homework = 4.2 hours/day
- 8 days of homework = 8.4 hours/day
- 20 days of homework = 21.0 hours/day
- 28 days of homework = 29.4 hours/day
Comparing the numbers, 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."
To answer the question, we need to compare the number of hours Marco and Maribella spend on homework per night.
Let's start by looking at Marco's table. We can see that for 3 days, he spends 3.25 hours, which gives us an average of 3.25/3 = 1.08 hours per day. Similarly, for 9 days, he spends 9.75 hours, which gives us an average of 9.75/9 = 1.08 hours per day. For 12 days, he spends 13.0 hours, which gives us an average of 13.0/12 = 1.08 hours per day. And for 30 days, he spends 32.5 hours, which gives us an average of 32.5/30 = 1.08 hours per day.
Now let's look at Maribella's table. For 4 days, she spends 4.2 hours, which gives us an average of 4.2/4 = 1.05 hours per day. For 8 days, she spends 8.4 hours, which gives us an average of 8.4/8 = 1.05 hours per day. For 20 days, she spends 21.0 hours, which gives us an average of 21.0/20 = 1.05 hours per day. And for 28 days, she spends 29.4 hours, which gives us an average of 29.4/28 = 1.05 hours per day.
As we can see, both Marco and Maribella spend an average of 1.08 hours per day and 1.05 hours per day on homework, respectively. Therefore, the statement "There is not enough information to tell who spends less time doing their homework" is correct.
