Question

At the beginning of the month, a video on a streaming service already had 2,130 views, and was getting 80 new views each day. Meanwhile, a video on a different service already had 1,800 views, and was getting 90 new views each day. Write an equation to show the number of days it would take for the two videos to have the same number of views. Use x
𝑥
as your variable.

Answer 1

Let x be the number of days. The equation is

2130 + 80x = 1800 + 90x.

Solving: 2130 − 1800 = 90x − 80x → 330 = 10x → x = 33 days.
