The total number of beads remains unchanged after Cole gives to Wesley.
Total number of beads
= 112 + 292
= 404
Total number of beads in the end
= 1 u + 1 u + 78
= 2 u + 78
2 u + 78 = 404
2 u = 404 - 78
2 u = 326
1 u = 326 ÷ 2 = 163
Number of beads that Cole must give to Wesley
= 163 - 112
= 51
Answer(s): 51
