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...

If the CD player sells regularly for $80 but is on sale for 20% off the sales price will now be $64. The equation used is ? x 0.8 = 20%. Think of teams of 10. 8+2 = 10 right? Now put transfer that to hundreds 80+20 = 100 or in this case 1 whole number. To get a certain percent off you need to x it by 0. (Other part of teams of 10) so if it was 63% off you would do ? x 0.37. If you want to keep it simple though just times the original number, in this case 80, by 0. And then the percentage ( 80 x 0.60 ) that’ll give you how much to take off of $80 to reach 20% off.
