sells pillows. For a sale, she marks them down 5%. If the original price of a pillow is $15.00, what is the sale price?

The required two expressions are

(1-0.05)P

0.95 P

Step-by-step explanation:

First method : Here, the original price of pillow = P,

She marks them down 5%

Thus, the selling price = P - 5% of P = P - 0.05 P = (1-0.05)P

Second method :

Since, some number is 100% of itself,

⇒ 100 % = P

⇒ 1 % = P/100 = 0.01 P

Also, by decreasing 5 % from 100 %

The remaining percentage = 100 - 5 = 95%

⇒ 95 % = 95 × 0.01 = 0.95 P

54
