To find the cost per song after the first 25 downloads, we need to calculate the additional fee per song.
First, let's calculate the additional fee for downloading the 28th song. We know that after downloading 25 songs, the total cost is $34.80. So the cost of the first 25 songs is $34.80.
To find the additional fee for the 28th song, we subtract the cost of the first 25 songs from the total cost of downloading 28 songs:
Additional Fee for the 28th song = Total cost for downloading 28 songs - Cost of the first 25 songs
= $34.80 - Cost of the first 25 songs
= $34.80 - $34.80
= $0.00
Since there is no additional fee for the 28th song, we can determine that the cost per song after the first 25 downloads is $0.00.
Now, let's calculate the cost of the website subscription.
To find the cost of the website subscription, we subtract the cost of the first 25 songs from the total cost of downloading 30 songs:
Cost of the website subscription = Total cost for downloading 30 songs - Cost of the first 25 songs
= $40.70 - $34.80
= $5.90
Therefore, the cost of the website subscription is $5.90.
