The total number of chocolate bars remains unchanged after Sam gives to Wesley.
Total number of chocolate bars
= 403 + 543
= 946
Total number of chocolate bars in the end
= 1 u + 1 u + 52
= 2 u + 52
2 u + 52 = 946
2 u = 946 - 52
2 u = 894
1 u = 894 ÷ 2 = 447
Number of chocolate bars that Sam must give to Wesley
= 543 - 447
= 96
Answer(s): 96
