Since you have a variable in the choices, you can just guess a number for I.
100 is always nice

I = 100
2%= 2
1%=1
==>2+[(100+1)/2]
2+50.5=52.5
(works out to C)

(fyi: I think its easier for people to respond if you embed your question as an image instead of attaching a document....use the 'add image to post' link right below this text box)
