25%=0.25
24*0.25=6

18 pairs are not black
You divide the two and that's your answer
The answer is 27 (hope this helps you)
Draw four boxes. Put five balloons in one box with the characters in them and write 1/4 under that box. Then draw five balloons in the other boxes, then draw one big box with the total amount of balloons in them.
The answer, at least what I got, is 17.375 . They'd have to open an eighteenth package because the extra .375 is not in the original package, so I would go with B .
