The total number of candy canes remains unchanged after Ivan gives to Howard.
Total number of candy canes
= 403 + 557
= 960
Total number of candy canes in the end
= 1 u + 1 u + 42
= 2 u + 42
2 u + 42 = 960
2 u = 960 - 42
2 u = 918
1 u = 918 ÷ 2 = 459
Number of candy canes that Ivan must give to Howard
= 557 - 459
= 98
Answer(s): 98
