The total number of candy canes remains unchanged after Gabriel gives to Will.
Total number of candy canes
= 339 + 514
= 853
Total number of candy canes in the end
= 1 u + 1 u + 43
= 2 u + 43
2 u + 43 = 853
2 u = 853 - 43
2 u = 810
1 u = 810 ÷ 2 = 405
Number of candy canes that Gabriel must give to Will
= 514 - 405
= 109
Answer(s): 109
