Hey there,
Each cake recipe would call for 

 cup of oil.
So if she is going to make 12 cakes, this would include that she
would need to use 12 cups of oil.

 would be your answer!
Hope this helps.

The straight line ON has the following equation :
(x - 18)/(x - 0) = (y - 12)/(y - 0)
Where (18,12) are coordinates of N and (0,0) are coordinates of O. 
x - 18/x = y - 12/y
-18y = - 12x
y =12x/18 - - - - - (a) 
The coordinates satisfy equation (a) are (7.5, 5)
Therefore D is the correct answer. 
Good luck
