PITIMTAINK 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 JWPLAYER.
