Answer 4

I'm not exactly sure how to answer this, but this is what I always do. I usually start taking the answers and plugging them in...
A. 0.05(118) + 0.25(38) = 21.6
5.9 + 9.5 = 21.6 I stop here because its obvious its no tthe answer

B. 0.05 (106) + 0.25(50) = 21.6
5.3 + 12.5 = 21.6 Same as A.

C. 0.5(87) + 0.25(69) = 21.6
4.35+17.25 = 21.6
21.6 = 21.6 Hurray its correct!
