plz I need this help 30 points What is the approximate percent decrease when a fish count goes down from 850 to 500?

Respuesta :

Increase=New number - Original number 
Increase=500-850=-350 
%increase=Increase/original number X 100 
%increase= -350/850 X 100 = -41.18% 

Number is negative because it is a percentage decrease.
