The total number of balls remains unchanged after Caden gives to Ivan.
Total number of balls
= 105 + 445
= 550
Total number of balls in the end
= 1 u + 1 u + 148
= 2 u + 148
2 u + 148 = 550
2 u = 550 - 148
2 u = 402
1 u = 402 ÷ 2 = 201
Number of balls that Caden must give to Ivan
= 201 - 105
= 96
Answer(s): 96
