Complete question :
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?
Answer:
Expression B: 0.8p ;
Expression D: p - 0.2p
Step-by-step explanation:
Given that:
Regular price = p dollars
Discount on price = 20%
Hence,
sale price = regular price - discounted price
Discounted price = 0.2 * p = 0.2p
Sale price = p - 0.2p
Or
Sale price = p - 0.2p = 0.8p
