So owl is a carnivorous bird. There are exceptions to this though, as some species such as Burrowing Owls may feed on seeds and fruits when prey is lacking, but for the most part they are carnivorous though.
There are 16 ounces in one pound. So to get one pound of cashews, you need to buy 16 ounces. If each ounce costs $.40: 16 ounces x $.40 per ounce = $6.40 So it costs $6.40 per pound of cashews. No, you can't buy a pound.
Solution #1: Use of one variable leading to a linear equation. Let x be the number of pounds of cashews. So, 150 - x will represent the number of almonds. Since each pound of the mixture cost 3 dollars, 150 pounds will cost 3 Ã 150 = 450 dollars.
