To determine which statement is correct regarding Marco's and Maribella's homework habits, we would typically need to analyze the data you've mentioned, such as the total hours of homework completed by each over a specific time period and how many nights those hours were spread across.
Since I don't have access to the tables that show their homework hours, I can’t directly evaluate their time spent per night. However, you can calculate this by taking the total hours for each person and dividing by the number of nights they spent doing homework.
If Marco's total hours divided by the number of nights is less than Maribella's, then "Marco spends less time on homework per night" would be the correct statement. Conversely, if Maribella's is less, then "Maribella spends less time on homework per night" is correct.
Review the totals and do the calculation to find out who spends more time on homework per night. If you can provide the numbers, I can help guide you further!
