Total number of marbles that Opal and Shannon shared = 100%
If Opal gave 126 marbles to Shannon, both would have the same number of marbles.
Number of marbles that each would have in the end
= 100% ÷ 2
= 50%
Number of marbles that Opal gave to Shannon
= 68% - 50%
= 18%
18% → 126
1% → 126 ÷ 18 = 7
Number of marbles that Shannon had
= 32%
= 32 x 7
= 224
Answer(s): 224
