To determine how many songs Joe can purchase with a $15 gift card, we can divide the total amount of the gift card by the cost per song.
Cost per song = $1.19
Total gift card amount = $15
Number of songs = Total gift card amount / Cost per song
Number of songs = $15 / $1.19 ≈ 12.61
Since Joe can only purchase whole songs, we round down to the nearest whole number, which is 12.
Therefore, Joe can purchase at most 12 songs.
