What units were they originally on?do you have a picture of the graph with it?
36.9. Just input the number in the equation and you get 4.5x18.2=36.9 as the volume
C and D are correct because 25 > 35 so that's C.
Its also D because they are not equal.
Hope this helps :)
50 times 28, you will get 1400.
If trying to mental calculate, I would :
28=20+8
50 times 20 = 1000
50 times 8 = 400
Then add them up to 1400.
