At the beginning of the month, a song on a streaming service already had 1,000 listens, and was getting 38 new listens each day. Meanwhile, a different song already had 900 listens, and was getting 40 new listens each day. what equation can help show the number of days it would take for the two songs to have the same number of listens

Answer 1

Let's assume we need "d" days for the two songs to have the same number of listens.

For the first song, the total number of listens after "d" days would be:

1,000 + 38d

For the second song, the total number of listens after "d" days would be:

900 + 40d

We can set these two expressions equal to each other:

1,000 + 38d = 900 + 40d

Then we can solve for "d":

38d - 40d = 1,000 - 900

-2d = 100

d = -50

This is a negative number, which doesn't make sense in this context.

Therefore, the two songs will never have the same number of listens since the second song is gaining listens at a faster rate than the first song.
