Percentage of mini cupcakes after Sean received from Peter
= 100% + 40%
= 140%
Percentage of Sean's mini cupcakes that Hilda had after receiving from Sean
= 50% x 140%
=
50100 x 140%
= 70%
Percentage of mini cupcakes that Sean had left after giving to Hilda
= 140% - 70%
= 70%
100% = 80
Number of mini cupcakes that Sean had left
= 70% x 80
=
70100 x 80
= 56
