Answer:
18.65%
Explanation:
We know
The regular price of each song is $0.89
0.89 x 15 = $13.35
Using a special discount, you download 15 songs for $10.86
What is the percentage of the discount?
We Take
13.35 - 10.86 = $2.49
Then we take
2.49 divided by 13.35, time 100 = 18.65%
So, the percent of the discount is 18.65%
