Answer:
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

Answer:
$17.12
Step-by-step explanation:
First let's find the normal cost with tax
7/100*19=133/100=$1.33
$19+$1.33=$20.33
Now we find the cost with tax for the Valentine's Day price
7/100*35=$2.45
$35+$2.45=$37.45
Now we subtract the normal cost from the Valentine's Day price
$37.45-$20.33=$17.12
