The total number of candy canes remains unchanged after Jack gives to Luis.
Total number of candy canes
= 452 + 665
= 1117
Total number of candy canes in the end
= 1 u + 1 u + 55
= 2 u + 55
2 u + 55 = 1117
2 u = 1117 - 55
2 u = 1062
1 u = 1062 ÷ 2 = 531
Number of candy canes that Jack must give to Luis
= 665 - 531
= 134
Answer(s): 134
