Percentage of candy canes after Elijah received from Ivan
= 100% + 20%
= 120%
Percentage of Elijah's candy canes that Rachel had after receiving from Elijah
= 50% x 120%
=
50100 x 120%
= 60%
Percentage of candy canes that Elijah had left after giving to Rachel
= 120% - 60%
= 60%
100% = 10
Number of candy canes that Elijah had left
= 60% x 10
=
60100 x 10
= 6
