The total number of sweets remains unchanged after Glen gives to Bobby.
Total number of sweets
= 350 + 578
= 928
Total number of sweets in the end
= 1 u + 1 u + 58
= 2 u + 58
2 u + 58 = 928
2 u = 928 - 58
2 u = 870
1 u = 870 ÷ 2 = 435
Number of sweets that Glen must give to Bobby
= 578 - 435
= 143
Answer(s): 143
