Answer:
Step-by-step explanation:
x-.20x
Lets say the hat cost $100
x=100
multiplying 100 by 20% which is .20 yields $20
S0 $20 is the discount which we subtract from the original price
100-20 and get the sale price of $80
They use a shortcut so you don't have to do the subtracting of the discount
They say if the price is being discounted subtract the discount from 1 and multiply that by the original amount
So in this case the discount percent was 20% = .20
Subtracted from 1
1-.20=.80
Since x is the original price we multiply x by the .80 to get
.80x
