Answer:
Option b. $7.68
Step-by-step explanation:
we know that
1) The music store is having a 15% off sale on all classical music cds
[tex]100\%-15\%=85\%=85/100=0.85[/tex]
If the cd has a price of $23.99
then
The price with 15% off sale is equal to
[tex]\$23.99(0.85)=\$20.39[/tex]
2) Lyell has a coupon for 20% off any classical music cd.
[tex]100\%-20\%=80\%=80/100=0.80[/tex]
If the cd with a 15% off sale has a price of $20.39
then
The price with a coupon for 20% off is equal to
[tex]\$20.39(0.80)=\$16.31[/tex]
Find the difference between the original price and the final price
[tex]\$23.99-\$16.31=\$7.68[/tex]
