Question

PLZ AWNSER!!!!!

Answer 1

39/130 = the percentage it now resides at.

 

       00.3

      ----------

130|39.0

       -390

       --------

            0

 

0.3 = 30%

So it currently resides at 30% of the previous price.

 

1 - 0.3 = 0.7

0.7 = 70%

There was a 70% price decrease.

 

 

Answer 2

% decrease = decrease / original

% decrease = (39 - 130) / 130

 

Can you calculate?
