Apple = 0.4$
Orange = 0.6$

Explanation:

Let #a=#apple and let #b=# orange
#=>#
#3a+4b=3.6#
#2a+5b=3.8#
#=>#
#6a+8b=7.2#
#6a+15b=11.4#
#=>#
#6a=-8b+7.2#
#6a=-15b+11.4#
#=>#
#-8b+7.2=-15b+11.4#
#=> 7b=4.2#
#=> b=0.6#
#=>#
#6a=-8*(0.6)+7.2 => 6a=2.4 => a=0.4#
#6a=-15*(0.6)+11.4 => 6a=2.4 => a=0.4#

If we got the same "a", we were right! :-)
