The total number of lollipops remains unchanged after Andy gives to Gabriel.
Total number of lollipops
= 330 + 595
= 925
Total number of lollipops in the end
= 1 u + 1 u + 57
= 2 u + 57
2 u + 57 = 925
2 u = 925 - 57
2 u = 868
1 u = 868 ÷ 2 = 434
Number of lollipops that Andy must give to Gabriel
= 595 - 434
= 161
Answer(s): 161
