The total number of candy canes remains unchanged after Jeremy gives to Eric.
Total number of candy canes
= 423 + 594
= 1017
Total number of candy canes in the end
= 1 u + 1 u + 49
= 2 u + 49
2 u + 49 = 1017
2 u = 1017 - 49
2 u = 968
1 u = 968 ÷ 2 = 484
Number of candy canes that Jeremy must give to Eric
= 594 - 484
= 110
Answer(s): 110
