To answer the question, we need to compare the number of hours Marco and Maribella spend on homework per night. Let's look at the table for Marco's homework:
Number of Days Number of Hours
3 3.25
9 9.75
12 13.0
30 32.5
Now let's look at the table for Maribella's homework:
Number of Days Number of Hours
4 4.2
8 8.4
20 21.0
28 29.4
To determine who spends less time on homework per night, we need to calculate the average number of hours they spend for each period. We can do this by dividing the total number of hours by the number of days for each period.
For Marco:
Average hours per night = Total hours / Number of Days
For Maribella:
Average hours per night = Total hours / Number of Days
Let's calculate the average hours per night for Marco:
For the first period: 3.25 hours / 3 days = 1.0833 hours per night
For the second period: 9.75 hours / 9 days = 1.0833 hours per night
For the third period: 13.0 hours / 12 days = 1.0833 hours per night
For the fourth period: 32.5 hours / 30 days = 1.0833 hours per night
Now, let's calculate the average hours per night for Maribella:
For the first period: 4.2 hours / 4 days = 1.05 hours per night
For the second period: 8.4 hours / 8 days = 1.05 hours per night
For the third period: 21.0 hours / 20 days = 1.05 hours per night
For the fourth period: 29.4 hours / 28 days = 1.05 hours per night
From the calculations, we can see that both Marco and Maribella spend an average of 1.0833 hours per night on their homework. Therefore, the correct statement is: Marco and Maribella spend equal time doing their homework.
