Answer:

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#

Answer:

#$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#
