Answer:
0.8p
Step-by-step explanation:
Let the Original price of the tennis racket bought by Natasha be p, if the mark down price is 20%
Discount price = 20% of p
Discount price = 0.2p
The amount Natasha paid = original price - markdown price
Amount Natasha paid = p - 0.2p
Amount Natasha paid = 0.8p
