The regular price of the sofa if 66% is given off, is $680.00
What is regular price?
The regular price of the sofa is the price at which it is sold without considering the coupon of 66%, in essence, it is 100% of the original price of the sofa, in short, if 66% is given off, then the sale price is 34% of the original price
34% of regular price=$231.20
1% of regular price=231.20/34

100% of regular price=$6.80*100
100% of regular price=$680
