The total number of mini cupcakes remains unchanged after Archie gives to Ken.
Total number of mini cupcakes
= 358 + 572
= 930
Total number of mini cupcakes in the end
= 1 u + 1 u + 56
= 2 u + 56
2 u + 56 = 930
2 u = 930 - 56
2 u = 874
1 u = 874 ÷ 2 = 437
Number of mini cupcakes that Archie must give to Ken
= 572 - 437
= 135
Answer(s): 135
