To determine how many songs Joe can purchase with his $15 gift card, we can divide the total amount of money he has by the cost of each song.
The cost per song is $1.19. We need to calculate how many songs he can buy with $15:
\[ \text{Number of songs} = \frac{\text{Total money}}{\text{Cost per song}} = \frac{15}{1.19} \]
Calculating this:
\[ \frac{15}{1.19} \approx 12.605 \]
Since Joe cannot purchase a fraction of a song, we need to round down to the nearest whole number. Therefore, he can purchase at most 12 songs.
Thus, the correct answer is:
A. at most 12 songs
