The total number of beads remains unchanged after Caden gives to Vincent.
Total number of beads
= 154 + 469
= 623
Total number of beads in the end
= 1 u + 1 u + 133
= 2 u + 133
2 u + 133 = 623
2 u = 623 - 133
2 u = 490
1 u = 490 ÷ 2 = 245
Number of beads that Caden must give to Vincent
= 245 - 154
= 91
Answer(s): 91
