Hi MHF.

I have an optimization problem:

A farmer can purchase two types of food products for his horses, one is called Lingo and the other is called Bingo.

Each bag of Lingo contains: 20gr of fats, 30gr of carbs and 5gr of proteins.

Each bag of Bingo contains: 10gr of fats, 30gr of carbs and 10gr of proteins.

The farmer needs a minimum of: 460gr of fats, 960 grams of carbs and 220 grams of proteins for his horses.

Each bag of Lingo costs 3000 and each bag of Bingo costs 3500.

How many of each bags should the farmer purchase to satisfy the minimum requirements?

I'm guessing that the constraint is the price, 3000 and 3500? I can do optimization problems with fences (the classic) but this one seems a lot different, but perhaps it isn't?

A little nudge would be appreciated!
