The price of an article at a sale was £4.50. This was 10% off. What was the price of the article before the sale?

Answer 1

Let x be the original price of the article.

We know that the sale price is £4.50, which is 10% off the original price.

So we can set up an equation:

x - 0.1x = 4.5

Simplifying:

0.9x = 4.5

Dividing by 0.9:

x = 5

Therefore, the original price of the article was £5.
