The regular price of an item at a store is p dollars. the item is on sale for 20% off the regular price. some of the expressions shown below represent the sale price, in dollars, of the item. expression a: 0.2p expression b: 0.8p expression c: 1 - 0.2p expression d: p - 0.2p expression e: p - 0.8p which two expressions each represent the sale price of the item?

Two expressions each represent the sale price of the item are:

Expression B : 0.8p is correct

Expression D: p - 0.2p is correct

Solution:

The regular price of an item at a store is p dollars

The item is on sale for 20% off the regular price

Therefore,

Regular price = p dollars

Discount = 20 % of regular price

Therefore,

Discount = 20 % of p

Sale price = Regular price - discount price

Sale price = p - 0.2p

Thus Expression D: p - 0.2p is correct

On solving, sale price = p - 0.2p

Sale price = 0.8p

Thus expression B : 0.8p is correct
