Percentage of caramel apples after Valen received from Tommy
= 100% + 40%
= 140%
Percentage of Valen's caramel apples that Fanny had after receiving from Valen
= 50% x 140%
=
50100 x 140%
= 70%
Percentage of caramel apples that Valen had left after giving to Fanny
= 140% - 70%
= 70%
100% = 40
Number of caramel apples that Valen had left
= 70% x 40
=
70100 x 40
= 28
