Final answer:
The Price family can spend 36 minutes on their screens each day.
Step-by-step explanation:
To find out how many minutes the Price family can spend on their screens each day, we need to subtract the movie's duration from their desired total screen time for the week. The movie was 84 minutes long, so the remaining screen time would be 300 minutes - 84 minutes = 216 minutes. To evenly distribute this over the next six days, we divide 216 minutes by 6 days. Therefore, the Price family can spend 36 minutes on their screens each day.
