Question

a sofa is on sale of 35% off. the sale price is $400. what is the regular price

Answer 1

Let x = regular price

Then to find 35% off that number:

x - 0.35x = 0.65x

But that number is the sale price:

0.65x = 400

To solve for x divide both sides by numerical coefficient of x:

x = 400 /0 .65 = $615.38 (rounded)
