Number of starfruits that Caden used
=
47 x 63
= 36
Number of starfruits that Caden had left
= 63 - 36
= 27
Number of apples that Caden used
=
38 x 128
= 48
Number of apples that Caden had left
= 128 - 48
= 80
Fraction of the fruits left that were apples
= 1 -
110=
910 Number of starfruits left = 1 u = 27
Number of apples left in the end
= 9 u
= 9 x 27
= 243
Number of apples that Caden bought
= 243 - 80
= 163
Answer(s): 163
