Answer 2

Answer:

14.28%

Step-by-step explanation:

1) you have many different formulas for % change the one i'm using is :

n$\frac{n-o}{o} =\frac{-x}{100\\}$

n= new quantity

o=old quantity

-x= % change(since the quantity decreases the numerator will be negative)

so

$\frac{30-35}{35} =\frac{-x}{100}$

30-35=-5

$\frac{-5}{35} =\frac{-x}{100}$

cross multiply:

-500=-35x

divide on both sides:

14.285=x

hope this helps!
