A. c=(2/9)b

B. c=(9/2)b

c. c=(2*9)b

d. 9*(2/b)

I think it is A.

I think this because I used an example of saying 18 was sold and plugged it into the equation and that would give me 4 donated.

Is this correct? If not can you explain how you find the answer.

c/b = 2/9

c = 2b/9 or A, you were right
