New price=$18550
Tax= 6%
Price before tax was added = x (Let the original price be x).
Tax=6% of x=6/100*x=3x/50
Therefore, Original price(x)+Tax(3x/50)=New price($18550)
x+3x/50=18550
LCM:50
50x/50x+3x/50=18550
53x/50=18550
53x=18550*50
53x=927500
x=927500/53
Therefore, x=17500
The original price is $17500.
