Percentage of candy canes after Jenson received from Billy
= 100% + 25%
= 125%
Percentage of Jenson's candy canes that Lucy had after receiving from Jenson
= 40% x 125%
=
40100 x 125%
= 50%
Percentage of candy canes that Jenson had left after giving to Lucy
= 125% - 50%
= 75%
100% = 20
Number of candy canes that Jenson had left
= 75% x 20
=
75100 x 20
= 15
