HEY CAN ANYONE PLS ANSWER DIS MATH QUESTION RQ

B) 77%; percent of decrease

Step-by-step explanation:

First, start by using the process of elimination:

From 31 in. to 7 in., it's probably a decrease.

So now you're down to choices:

B) 77%; percent of decrease

and

C) 23%; percent of decrease.

Now, you can use a ratio:

31 in           100%

   =    

 7 in              x%

Then, cross multiply:

31x = 7 (100)

31x = 700

x = 22.58064...

x ≈ 22.58%

So 7 in. is about 23% of 31 in. To find the difference between 31 in. and 7 in., subtract the amounts to find the change between them:

100% – 22.58...% = x% of change

                               ≈ 77.4% of change

a=r

d=q

c=p

b=s

hope this !
