Jacy paid $15.48 to download 12 songs last month. She paid the same amount for each song and also had to spend $5.04 to enroll in the music purchasing program.

Part A
Let s represent the amount that Jacy paid for each song she downloaded.
Which equation could you use to find the value of s?
12s = 15.48
15.48 + s = 12 + 5.04
12 + s = 15.48 + 5.04
12s + 5.04 = 15.48
