Answer:

The expression that can be used is 0.80x

Explanation:

Let

x ----> original price of an item

Remember that


100\%-20\%=80\%

That means---> the sale price is 80% of the original price

To find out the sale price, determine the 80% of the original price


80\%=80/100=0.80 ----> percentage in decimal form

Multiply the original price by the percentage in decimal form to obtain the sale price

so


0.80x
