Answer:
The normal undiscounted price of the book is $17.25.
Step-by-step explanation:
This question can be solved using a rule of three.
After a 35% discount, a book costs $11.21
This means that $11.21 is 100-35 = 65% = 0.65 of the original price x.
How much is x, which is 100% = 1?
$11.21 - 0.65
$x - 1



The normal undiscounted price of the book is $17.25.
