Sholpan [36]

Answer:

The expression that can be used is 0.80x

Step-by-step 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

$0.80x$
