Problem-solving and inequalities

[amalalfa]

I've been struggling with this problem trying to come up with a system of inequalities. The problem goes like this:

The director of a zoo would like to feed the animals in the zoo a minimum per day of 120 kg of proteins, 90 kg of lipids and 60 kg of carbohydrates. Two combinations are prepared for marketing in a bag A and bag B with the following characteristics in the table below:

Proteins Lipids Carbs Cost
Bag A contains : 3 kg 3 kg 1 kg @ : 10€
Bag B contains : 2 kg 1 kg 2 kg @ : 5€


Translate the above into a system of inequalities (let x be the number of sacs A and y be the number of sacs B
That can be purchased/bought).

Then find out how many bags will he need to spend 200€ a day ? for 400€?

I would appreciate any help I can get..
Thanks

Please share with us your work/thoughts - even if those are incomplete or you think those are incorrect - so that we know where to begin to help you.

For example: condition 1: minimum per day of 120 kg of proteins

x * 3 + y * 2 ? 120.........................................(1)

That is your first inequality.

Now continue.....
