Question

The price (p) of an item is marked down 20%. Write two expression that represent the sale price.

Answer 1

Answer:

So I would say any one of the following:

(1-.2)p

p-.2p

.8p

Step-by-step explanation:

If you start with price p and you are getting it marked down 20%, then you are paying (100-20)%p.

So you have:

(1-.2)p

or if you use distributive property:

1(p)-.2(p)

p-.2p

or if you combine the like terms:

.8p
