Percentage of mini cupcakes after Archie received from Daniel
= 100% + 40%
= 140%
Percentage of Archie's mini cupcakes that Jane had after receiving from Archie
= 50% x 140%
=
50100 x 140%
= 70%
Percentage of mini cupcakes that Archie had left after giving to Jane
= 140% - 70%
= 70%
100% = 20
Number of mini cupcakes that Archie had left
= 70% x 20
=
70100 x 20
= 14
