The total number of mini cupcakes remains unchanged after Julian gives to Warren.
Total number of mini cupcakes
= 330 + 669
= 999
Total number of mini cupcakes in the end
= 1 u + 1 u + 41
= 2 u + 41
2 u + 41 = 999
2 u = 999 - 41
2 u = 958
1 u = 958 ÷ 2 = 479
Number of mini cupcakes that Julian must give to Warren
= 669 - 479
= 190
Answer(s): 190
