To find the regular price of the sofa, we can set up the equation:
Let x be the regular price of the sofa.
68% of x (regular price) is equal to $425 (sale price).
So, we have:
0.68x = $425
To find x, we divide both sides of the equation by 0.68:
x = $425 / 0.68
x ≈ $625
So, the regular price of the sofa is approximately $625.
