Percentage of candy canes after Albert received from Caden
= 100% + 40%
= 140%
Percentage of Albert's candy canes that Penelope had after receiving from Albert
= 50% x 140%
=
50100 x 140%
= 70%
Percentage of candy canes that Albert had left after giving to Penelope
= 140% - 70%
= 70%
100% = 10
Number of candy canes that Albert had left
= 70% x 10
=
70100 x 10
= 7
