Question 34933
Hello!
Let's call X to the original price of the book.

The price was first reduced by 25%. This means that the sale price is now 75% of the original price. Therefore, the sale price has now become {{{0.75X}}}

Now, a further 40% reduction is applied. This implies that the new price is 60% of what it used to be. Since it used to be {{{0.75X}}}, then the new price must be {{{0.6*(0.75X) = 0.45X}}}

Therefore, the final price of the book is 45% of the original price.


I hope this helps!
