According to the question, If “x” represents the full price of an item then expression to represent the final cost of an item that is 20% off is:-

now as we know, when we apply discount percent on total amount of item then we get discount amount

so, let the discount amount=y

so now, x*20%=y

x*20/100=y

x*1/5=y

x=5y (Answer)
