Hai, Brainiac!
Great question!
Basically to find the answer, first you add the number of each marble there is.
5 black marbles + 9 white marbles + 2 red marbles = 16 marbles altogether.
Red marbles to the total number of marbles altogether is 2:16, a ratio.
Simplified, that would be 1:8 marbles, or, answer choice B, so your answer would be 1/8 :D
Hope this helps!

Step-by-step explanation:
I hope it's correct... Ahhh... Now it's long enough to post
If B is the midpoint of AC, that means that the distances from A to B and B to C are the same. The distance from A to B is 8x + 4, and the distance from B to C is 10x - 6, so we can set these two equivalent:
8x + 4 = 10x - 6
Solving for x:
4 = 2x - 6 (subtract 8x from both sides)
10 = 2x (add 6 to both sides)
5 = x (divide both sides by 2)
So, x = 5, which is the second option given.
Well the answer would be $18.8784 but if you want it to be shorter it would be $18.88 because you multiply 17.48 and 0.08 and get 1.3984 and then you add it to $17.48
