Hannah buys some shoes in sale marked 40% off she pays 27 for the shoes what price were the shoes the shoes orginally
mezya [45]

Given:

The price of shoes after discount = 27

Discount % = 40%

To find:

The original price of shoes before discount.

Solution:

Let x be the original price of shoes before discount.

The price of shoes after 40% discount is

\text{New price}=x-\dfrac{40}{100}\times x

\text{New price}=x-0.4x

\text{New price}=0.6x

The price of shoes after discount = 27

27=0.6x

\dfrac{27}{0.6}=x

45=x

Therefore, the original price of the shoes is 45.
