Could someone please help me with this problem. I'm having a bit of trouble. It would be much appreciated. Thanks.


A dog food manufacturer makes three types of dog food mix. Each type is sold in bags containing 5 kg with the ratio of meat : rice : vegetables being as follows:
Mix A Meaty Lumps 5 : 3 : 2
Mix B Balanced Lumps 1 : 1 : 3
Mix C Vegetarian Lumps 0 : 3 : 2
The manufacturer orders 3350 kg of meat, 4850 kg of vegetables and 4300 kg of rice for a particular run. The run is a simple mix and involves no weight loss for any of the ingredients and all quantities ordered are exactly used up. If the run produces x bags of Mix A, y bags of Mix B and z bags of Mix C write three equations that apply and solve them to find x, y and z.
