Answer:
$96 is the original price of book
Step-by-step explanation:
keep the unknown value as X
(19.2/X)*100 = 20%
19.2/X = 0.2
19.2/0.2 = X
X = 96
The original price of the book is $24.
When there is a sales, the price of items become cheaper. Items become less expensive when there is a sale.
When there is a 20% reduction in the price of the book, the book becomes 80% (100 - 20%) cheaper. In order to determine the original price of the book, divide the sales price by 80%
Original price = $19.20 / 80%
= $19.20 / 0.8
= $24
