Answer:

3w+10>2w+15

Step-by-step explanation:

If Jerry initially releases 10 videos a week and creates an additional 3 each week, he will create a total of 3w+10 videos, where w is the number of weeks. If Martin initially releases 15 videos a week and creates an additional 2 each week, he will create a total of 2w+10 videos, since w is maintained. Therefore, the inequality \fbox{$3w+10>2w+15$} can be used to find who creates more videos, where w is the number of weeks.
