Answer 19

No, sorry though. I'm only in 9th grade.

Answer 20

I keep doing that and nothing comes out right. ;(

Answer 21

This is 9th grade math, I just didn't have segment 1 done yet.

Answer 22

@Hero can you pleasseee help?

Answer 23

Well when you solve it you get f(x)=90.x
So I'm assuming you solve for the % difference between 72 and 90?

Answer 24

I thought it was 75% but I wasn't sure.

Answer 25

@jlg030597 do u know?

Answer 26

Well to find the difference you have to first subtract 72 from 90 so 90-72=?

Answer 27

I'm gonna close this and re ask again :)

Answer 28

90-72= 18
The next step is the find the average of 90 and 72. To find that you do 90+72/2=117
Now you do 117/18=6.5

So the percent increase would be 6.5%

Answer 29

I'm not sure If it's right though because I'm still not sure if you're supposed to find the difference between 72 &90.

Answer 30

Thanks so much! I have to go now! I got a percentage change of 25% and 30%.
