The total number of mini cupcakes remains unchanged after Cody gives to Lee.
Total number of mini cupcakes
= 475 + 654
= 1129
Total number of mini cupcakes in the end
= 1 u + 1 u + 59
= 2 u + 59
2 u + 59 = 1129
2 u = 1129 - 59
2 u = 1070
1 u = 1070 ÷ 2 = 535
Number of mini cupcakes that Cody must give to Lee
= 654 - 535
= 119
Answer(s): 119
