The total number of candy canes remains unchanged after Justin gives to Zeph.
Total number of candy canes
= 423 + 602
= 1025
Total number of candy canes in the end
= 1 u + 1 u + 53
= 2 u + 53
2 u + 53 = 1025
2 u = 1025 - 53
2 u = 972
1 u = 972 ÷ 2 = 486
Number of candy canes that Justin must give to Zeph
= 602 - 486
= 116
Answer(s): 116
