Based on the information given in the tables, it is not possible to determine who spends less time doing their homework. Therefore, the correct statement is: There is not enough information to tell who spends less time doing their homework.
Based on the tables provided, the correct statement is:
Maribella spends less time on homework per night.
To answer the question, you need to compare the number of hours Marco and Maribella spend on homework per night.
According to the tables, Marco's homework for 3 days takes 3.25 hours, 9 days takes 9.75 hours, 12 days takes 13.0 hours, and 30 days takes 32.5 hours.
Maribella's homework for 4 days takes 4.2 hours, 8 days takes 8.4 hours, 20 days takes 21.0 hours, and 28 days takes 29.4 hours.
To determine who spends less time doing their homework per night, we need to calculate the average number of hours per day for each person. We can do this by dividing the total number of hours by the number of days.
For Marco, the average number of hours per day is:
- For 3 days: 3.25 / 3 = 1.0833 hours per day
- For 9 days: 9.75 / 9 = 1.0833 hours per day
- For 12 days: 13.0 / 12 = 1.0833 hours per day
- For 30 days: 32.5 / 30 = 1.0833 hours per day
For Maribella, the average number of hours per day is:
- For 4 days: 4.2 / 4 = 1.05 hours per day
- For 8 days: 8.4 / 8 = 1.05 hours per day
- For 20 days: 21.0 / 20 = 1.05 hours per day
- For 28 days: 29.4 / 28 = 1.05 hours per day
Based on these calculations, it is evident that both Marco and Maribella spend an average of 1.0833 hours per day on homework. Therefore, the correct statement is: Marco and Maribella spend equal time doing their homework.
