Question

A sofa in a 25% off sale costs £330
How much does it normally cost?

Answer 1

Answer: £440 is the original price of the sofa

Explanation:

Let s represent the normal price of the sofa.

After applying a 25% discount, the sale is 75% the normal price, and we can set up the equation as such.

0.75s = £330

Now solve for s.

s = £330 / 0.75

s = £440

So, the original cost of the sofa is £440.
