Hey,
Solution,
Marked price(MP)= $ 80
Discount percent= 20%
Now,
Discount amount=discount percent of MP
= 20% of 80
=20/100*80
= $ 16
Again,
Selling price(SP)=MP - Discount amount
=$80 -$16
=$64
So,the sale price of the CD player is $ 64.
Hope it helps...
Good luck on your assignment....
Stay safe...
