Percentage of mini cupcakes after Jeremy received from Glen
= 100% + 40%
= 140%
Percentage of Jeremy's mini cupcakes that Kylie had after receiving from Jeremy
= 50% x 140%
=
50100 x 140%
= 70%
Percentage of mini cupcakes that Jeremy had left after giving to Kylie
= 140% - 70%
= 70%
100% = 40
Number of mini cupcakes that Jeremy had left
= 70% x 40
=
70100 x 40
= 28
