The total number of mini cupcakes remains unchanged after Tom gives to Perry.
Total number of mini cupcakes
= 366 + 536
= 902
Total number of mini cupcakes in the end
= 1 u + 1 u + 52
= 2 u + 52
2 u + 52 = 902
2 u = 902 - 52
2 u = 850
1 u = 850 ÷ 2 = 425
Number of mini cupcakes that Tom must give to Perry
= 536 - 425
= 111
Answer(s): 111
