To calculate the amount of time left to play video games, we need to subtract the time spent on band practice, dinner, and homework from the time school is out at 3:50 pm until the bedtime at 10 pm.
First, we need to convert all the given times to a common unit, which will be minutes.
Band practice: 2 1/2 hours = 2.5 * 60 = 150 minutes
Dinner: 3/4 of an hour = 0.75 * 60 = 45 minutes
Homework: 1 1/4 hours = 1.25 * 60 = 75 minutes
Next, we calculate the total time spent on band practice, dinner, and homework: 150 minutes + 45 minutes + 75 minutes = 270 minutes.
Now, we subtract the time spent from the time available: 10:00 pm - 3:50 pm = 6 hours and 10 minutes = 6 * 60 + 10 = 370 minutes.
Finally, we need to subtract the time spent on activities from the total time available: 370 minutes - 270 minutes = 100 minutes.
Therefore, about 100 minutes are left to play video games, which is equal to 1 hour and 40 minutes. So, the correct answer is C. 1 hour.
