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
