Final answer:
To find the sale price of an article reduced by 12 percent, calculate 12% of the normal price, subtract it from the normal price, and multiply the normal price by 0.88. For a normal price of $100, the sale price would be $88.
Step-by-step explanation:
If an article is reduced by 12 percent, to find the sale price, you first calculate the discount amount and then subtract it from the normal price. Let's assume the normal price of the article is $P. The discount amount would be 12% of the normal price, which can be calculated by multiplying the normal price by 0.12 (12/100).
The discount amount is therefore 0.12 × $P. To find the sale price, subtract the discount amount from the normal price:
Sale Price = Normal Price - Discount Amount
Sale Price = $P - (0.12 × $P)
Sale Price = $P(1 - 0.12)
Sale Price = $P(0.88)
To get the final sale price, just multiply the normal price by 0.88. For example, if the normal price is $100, the sale price would be 100 × 0.88 = $88.
