you have a subscription to a music website that allows you to download 25 songs from the site each month. You are charged an additional fee after the first 25 songs are downloaded. After downloading 28 songs, you paid a total of $34.80. After downloading 30 songs, you paid a total of $40.70.
a: what is the cost per song after the first downloaded?
b: what is the cost of the website subscription?
done, check earlier post
