In store b, downloading 15 songs cost 9.75,what is the cost (in dollars)per song? at the rate, what is the cost of 18 songs? challange: how many song can you buy with $20.00? (answer both )

15 songs cost $9.75.
To find the cost of each song, divide the two numbers.
9.75/15 = 0.65
Each song costs $0.65.

For 18 songs,
18 × 0.65 = 11.7
18 songs cost $11.70.

To find the number of songs you can buy with $20 (x=number of songs),
0.65x = 20
x = 30.8
Since you're buying songs, you can only have a whole number. This means you must round down to 30.
You can buy 30 songs with $20.00.
