Answer: $12
Explanation:
To find the sale price of a bottle of perfume that is originally priced at $40 and is now 70% off, you can follow these steps:
- Calculate the discount amount: Multiply the original price ($40) by the discount percentage (70%) to find the discount amount.
 
- Discount amount = $40 * 70% = $28
-  Subtract the discount amount from the original price to find the sale price.
 
 Sale price = $40 - $28 = $12
 This means that after applying a 70% discount, the price of the perfume is reduced to $12. 
OR
you can find 10% of $40, which is 4
to get 10% divide the number given by 10 
10%= 4 
Since in this case we are to find 70% of it then you multiply 4 by 7 which is $28 
Then you subtract the discount price from the original price to find the sale price
Sale price= $40-$28= $12
