Marcus is inventing a new cookie recipe. He'd like the recipe to contain both walnuts and gourmet chocolate - gourmet cookie recipes

The nuts are sold at $ 1.40 a pound, and selling gourmet potato chips for $ 2.80 per pound. How many kilos of mixed nuts with 2 pounds of gourmet chips to get a mixture for the sale of $ 1.68 per pound?
