PLEASE HELP ME WITH THIS! FREE POINTS! JB's music store is offering 20% discount on all CDs and DVDs, meaning 80% of the price remains. If the discounted price of a CD is $16.80, then the original price of the CD was $

Step-by-step explanation:

If it's 20% off, then it's 80% of the original price (100% is full price). Let's call the original price P, for Price. 80% of something is the same as multiplying that something by .8 (since you can always multiply something by one, and .8 is 80% of 1).

Eighty percent of the original price is $16.80, thus .8 (P) = $16.80

You need to solve for P, so you need to get P by itself on one side. The easiest way is to get rid of the .8. Divide both sides by .8 and you get P = $16.80/.8, or $21.00, so the original price (P) is $21.00

To check this, get a calculator and solve for 80% of 21.00 (if you don't have a percent sign, just type 21.00*.8). Hope this helped!
