I estimate a sum when I'm buying things and don't have ready access to a pencil, paper, or calculator.
Almonds are sold in bulk for $5.60 per pound (16 ounces) o in a 12 ounce package for $3.60. If Pierre only needs 12 ounces for a recipe, how much would he save by purchasing the 12-ounce package instead of 12 ounces of almonds sold in bulk?
