Judy bought 1lb6oz of almonds, 2lb3oz of walnuts, and 8oz of cashews. How many pounds of nuts did Judy buy?

1 pound 6 ounces plus 2 pounds 3 ounces would total 3 pounds and 9 ounces. Then, add the 8 ounces of cashews to the 9. 9 + 8 = 17. There are 16 ounces in a pound, so we now have an additional 1 pound and 1 ounce. This totals at 4 pounds and 1 ounce.
