Percentage of mini cupcakes after Albert received from Vincent
= 100% + 20%
= 120%
Percentage of Albert's mini cupcakes that Xylium had after receiving from Albert
= 50% x 120%
=
50100 x 120%
= 60%
Percentage of mini cupcakes that Albert had left after giving to Xylium
= 120% - 60%
= 60%
100% = 40
Number of mini cupcakes that Albert had left
= 60% x 40
=
60100 x 40
