t is the total increase of the followers made up --> t = '____'
- 3 followers for every 'h' (hashtag)
--> '3h' is the increase of followers for every hastag
- 5 followers for every 'i' (influencer)
--> '5i' is the increase of followers for every influence
Now lets put it together
t = 3h + 5i ; fourth choice
Hope it helps!
