Percentage of caramel apples after Luke received from Archie
= 100% + 40%
= 140%
Percentage of Luke's caramel apples that Fiona had after receiving from Luke
= 50% x 140%
=
50100 x 140%
= 70%
Percentage of caramel apples that Luke had left after giving to Fiona
= 140% - 70%
= 70%
100% = 50
Number of caramel apples that Luke had left
= 70% x 50
=
70100 x 50
= 35
