Answer 2

Given: Stephanie buys a book in a sale for $19.20. This sale price is after a reduction of 20%.

To find: We have to find the original price of the book.

Solution:

Let the original price of the book be $x.

The sale of the book is 20%.

So, the reduced price of the book is as follows-

$x - \frac{x \times 20}{100} \\ x - \frac{x}{5} \\ \frac{4x}{5}$

The sale price of the book is 4x/5.

This price is equal to $19.20.

Thus we can write-

$\frac{4x}{5} = 19.20 \\ x = 24$

The value of x is 24.

The original price of the book is $24.
