Question

JB's music store is offering a 20% discount on all CD's and DVD's, meaning 80% of the price still remains. If the discounted price of a CD is $16.80, what was the original price?

Answer 1

By dividing the discounted price $16.80 by 0.80, we determine that the original price of the CD was $21.00 before the 20% discount was applied.

Step-by-step explanation:

The question asks to determine the original price of a CD before a 20% discount was applied, with the given discounted price being $16.80. To solve this, we first recognize that 80% of the original price is equal to $16.80. We can represent the original price as 'P.'

The equation modeling the situation is: 0.80 * P = $16.80.

To find 'P,' the original price, divide both sides of the equation by 0.80:

P = $16.80 / 0.80

P = $21.00

Therefore, the original price of the CD was $21.00.

Answer 2

16.80·0.20=3.36
So the answer is $3.36.
