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
