the bandanna was originally $4

Explanation:

%50 is the same as 1/2 so if you solve x=n+x*m where m is the fraction equivalent of the percentage and n is the price after the discount, x=2+x/2 so if you take x/2 from each side you get x/2=2 which means x=4

$4

Explanation:

YOu can use direct proportion.

100%-50% = 50%

The price of $2 represents 50%, how much is the 100%?

2/50 = x/100

x = (100xx2)/50

x =$4

YOu could also have seen the the values on the right are double the values on the left.

2/50 xx 2/2 = x/100

x = 2xx2=4
