Percentage of mini cupcakes after Jack received from Vincent
= 100% + 20%
= 120%
Percentage of Jack's mini cupcakes that Kimberly had after receiving from Jack
= 50% x 120%
=
50100 x 120%
= 60%
Percentage of mini cupcakes that Jack had left after giving to Kimberly
= 120% - 60%
= 60%
100% = 80
Number of mini cupcakes that Jack had left
= 60% x 80
=
60100 x 80
