Answer:
Given the statement: "A new dog leash with an attached flashlight was on sale for 20% off and the original price was $16.50".
Then, we have
the original price = $16.50.
Sale off = 20%
Discounted price states the reduced prices or something being sold at a price lower than that item is normally sold.
Then;
20% of $ 16.50 =
![(20)/(100) * 16.50 =(20 * 16.50)/(100) =(330)/(100) = \$3.3](https://img.qammunity.org/2019/formulas/mathematics/high-school/j86y7birkb3biydw1df2lujbthklmmh5nw.png)
Therefore,
the discounted price = $16.50 -$ 3.3 = $ 13.20
