To determine which area Tony might consider changing to address his problem of not finishing his homework on time, we need to look for an area where he is spending a significant amount of time that could be reduced.
From the provided activities and their time estimates:
- Math homework: 1 hour
- Lunch: 30 minutes
- Playing video games: 3 hours 30 minutes
- English homework: 45 minutes
The most significant time allocation is for playing video games at 3 hours and 30 minutes. If Tony reduces the time spent on video games, he can free up more time to focus on his homework and finish it on time. Thus, he might consider changing the time he spends on playing video games to address his homework completion issue.
