Answer: Let amount of chocolate, be C, and amount of other candy, V

Then: C + V = 15 ------- C = 15 � V ------- eq (i)

Also, C(1.8) + V(3) = 15(2.2)_____1.8C + 3V = 33 ------ eq (ii)

1.8(15 � V) + 3V = 33 ------- Substituting 15 � V for C in eq (ii)

 27 � 1.8V + 3V = 33

     � 1.8V + 3V = 33 � 27

                1.2V = 6

V, or amount of other candy in 15 kg mixture = 10 kg

C = 15 � 5 ------- Substitute 5 for V in eq (i)

C, or amount of chocolate in 15 kg mixture = 10 kg
