The total number of balls remains unchanged after Perry gives to Caden.
Total number of balls
= 264 + 405
= 669
Total number of balls in the end
= 1 u + 1 u + 63
= 2 u + 63
2 u + 63 = 669
2 u = 669 - 63
2 u = 606
1 u = 606 ÷ 2 = 303
Number of balls that Perry must give to Caden
= 303 - 264
= 39
Answer(s): 39
