Question

a pair of shoes is on sale for 30% off. the original price is p. which expression can be used to find the price of the shoes after the discount?

Answer 1

Answer:

Discounted price= 0.7 p

Step-by-step explanation:

Original price = p

Since we are given that 30 % is off on the price

So, 30 % of p

$\frac{30}{100} \times p$

$0.3p$

So, the discount is of amount 0.3p

So, the discounted price = Original price - Discount amount

So,the discounted price = p-0.3p

Discounted price= 0.7 p

Hence expression can be used to find the price of the shoes after the discount is 0.7p

Answer 2

Original price = p
Discount price = p * (30/100)
                        = 0.3p
Price after the discount
p - 0.3p
0.7p
