Users on Social Media
By Sarav Chouhan
Let's take a look at the popularity of the two most competitive social media networks, Instagrad and Twittrit. Both of them are rapidly gaining more and more users as months progress. Instagrad and Twittrit were both founded on January 2014. Instagrad had started out with 150 users in the first two weeks and gained more users as the months passed. Twittret, however, didn’t get any users until after the first month. The question is, which one has more user accounts now and as a result, is more popular.
classification of variables
- Let x represent the number of months since the release date
- Let y represent the number of users that joined
Since Instagrad had 575 new users in one month, 575x is the constant multiple. Since Instagrad had 150 users in under a month (0 months), 150 is the constant value that gets added to the rest of the equation. Therefore, y = 575x + 150 (a partial variation).
Since Twittrit had 155 users joined in one month, the constant multiple is 155x. Since it had 0 users in under a month (0 months), there is no constant value that needs to be added to the rest of the equation. Therefore, y = 155x (a direct variation).
Total number of Instagrad users: y = 200x + 150
Total number of Twittrit users: y = 230x

point of intersection
- both networks have the same number of users (1150 users) in May (5 months after the release dates)
200x + 150 - 230x = 0
200x - 230x = -150
-30x = -150
-30x / -30 = -150 / -30
x = 5
