Answer:
$142.86
Step-by-step explanation:
In order to know the original price of the sound bar, it is best to write the problem above into a mathematical sentence first.
Given: $30 = the amount you were able to save
21% = the discount (this means that $30 is the 21% discount)
Let x be the original price of the sound bar.
The mathematical sentence is:
$30 is 21%(0.21) of x
x=[tex]\frac{30}{0.21}[/tex]
x= $142.857 or $142.86 (once rounded off to the nearest hundredths)
So, the original price of the sound bar before the discount is $142.86
