Percentage of mini cupcakes after Asher received from Mark
= 100% + 25%
= 125%
Percentage of Asher's mini cupcakes that Elyse had after receiving from Asher
= 40% x 125%
=
40100 x 125%
= 50%
Percentage of mini cupcakes that Asher had left after giving to Elyse
= 125% - 50%
= 75%
100% = 40
Number of mini cupcakes that Asher had left
= 75% x 40
=
75100 x 40
= 30
