Option C: $30 is the original price of book.
Step-by-step explanation:
Let the original price of book be x
Given that:
Sale price = x - 40% of x
As it is given that the sale price was $18
So,
$18 = x - 40% of x
By simplifying:
$18 = x - 0.4x
$18 = 0.6x
Dividing both sides by 0.6:
x = $18/0.6
x = $ 30
So the original price of book will be $30
