Maribella spends less time on homework per night.
To determine who spends less time on homework per night, we need to compare the average number of hours each of them spends on homework per day.
For Marco, the average number of hours of homework per day is calculated by dividing the total number of hours by the total number of days:
3.25 hours / 3 days = 1.083 hours per day
9.75 hours / 9 days = 1.083 hours per day
13.0 hours / 12 days = 1.083 hours per day
32.5 hours / 30 days = 1.083 hours per day
For Maribella, the average number of hours of homework per day is calculated by dividing the total number of hours by the total number of days:
4.2 hours / 4 days = 1.05 hours per day
8.4 hours / 8 days = 1.05 hours per day
21.0 hours / 20 days = 1.05 hours per day
29.4 hours / 28 days = 1.05 hours per day
Comparing the average number of hours per day, we can see that Marco and Maribella both spend approximately 1.083 hours per day on homework. Therefore, the correct statement is: "There is not enough information to tell who spends less time doing their homework."
To answer the question, we need to compare the number of hours Marco and Maribella spend on homework per night. Looking at the tables:
For Marco:
- In 3 days, Marco does 3.25 hours of homework.
- So, per day, Marco does 3.25 hours / 3 days = 1.08 hours of homework.
For Maribella:
- In 4 days, Maribella does 4.2 hours of homework.
- So, per day, Maribella does 4.2 hours / 4 days = 1.05 hours of homework.
Comparing the per-night homework hours, we can see that Marco spends slightly more time on homework per night (1.08 hours) compared to Maribella (1.05 hours).
Therefore, the correct statement is:
Marco spends less time on homework per night.
