tekilochka [14]

The price of the product before promotional sales was 500,000.

<h3>How to find out what the previous price was?</h3>

To find what the previous price of the product was, we must take into account that we know that 87% of the value is equal to 435,000. So to find out how much the 13% (discount) that the product had is equivalent to, we do the following operation:

435,000 × 100 ÷ 87 = 500,000

So we know that the 13% discount was 65,000
