1. To find the price of a single song, divide the total paid by the number of songs purchased: $10.20 / 12 = $0.85 per song.

2. First way to calculate the price of 15 songs: Since each song costs $0.85, multiply that by 15: $0.85 * 15 = $12.75.

Second way: Since the price of 12 songs is $10.20, divide $10.20 by 12 to find the price of one song, then multiply by 15: ($10.20 / 12) * 15 = $12.75.

3. To find out how many songs Mia bought with $5.95, divide the amount she paid by the price per song: $5.95 / $0.85 = 7 songs (rounded down).

4. With $20, and each song priced at $0.85, let's see how many songs can be bought: $20 / $0.85 = approximately 23.53 songs. Since you can't buy a fraction of a song, you can buy 23 songs with $20, but not 25.
