Marco and Maribella spend equal time doing their homework.

Answer 1

To determine who spends less time on homework per night, we calculate the average number of hours spent on homework per day for both Marco and Maribella.

Marco’s Homework:

• For 3 days: 3.25 hours / 3 days = 1.08 hours/day
• For 9 days: 9.75 hours / 9 days = 1.08 hours/day
• For 12 days: 13.0 hours / 12 days = 1.08 hours/day
• For 30 days: 32.5 hours / 30 days = 1.08 hours/day

Average time Marco spends is 1.08 hours per day.

Maribella’s Homework:

• For 4 days: 4.2 hours / 4 days = 1.05 hours/day
• For 8 days: 8.4 hours / 8 days = 1.05 hours/day
• For 20 days: 21.0 hours / 20 days = 1.05 hours/day
• For 28 days: 29.4 hours / 28 days = 1.05 hours/day

Average time Maribella spends is 1.05 hours per day.

Now, comparing the two averages:

• Marco: 1.08 hours/day
• Maribella: 1.05 hours/day

Since Maribella spends less time on homework per night than Marco, the correct statement is:

Maribella spends less time on homework per night.
