At the beginning of the month, a song on a streaming service already has 1000 listens, and was getting 38 new listens each day. Meanwhile a different song already had 900 listens
, and was getting 45 new listens each day.
After 10 days, the first song would have 1000 + (38 x 10) = 1380 listens.
After 10 days, the second song would have 900 + (45 x 10) = 1350 listens.
Therefore, after 10 days, the first song would have more listens than the second song.
