2. 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

   Step-by-step explanation: If incorrect Sorry, Hope it helps!!
