Solution
Almonds = 1 pound 6 ounces
Walnuts = 2 pounds 3 ounces
Cashew = 8 ounces
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.
Therefore the totals weight is 4 pounds and 1 ounce.
