Final answer:
To find how many more pounds of walnuts Nina bought than almonds, subtract the weight of almonds (1.83 pounds) from the weight of walnuts (3.45 pounds), which equals 1.62 pounds.
Step-by-step explanation:
The question asks us to calculate the difference in weight between the walnuts and the almonds that Nina bought. To find this, we subtract the weight of the almonds from the weight of the walnuts. The calculation is as follows:
Weight of walnuts: 3.45 pounds
Weight of almonds: 1.83 pounds
Difference in weight (walnuts - almonds): 3.45 pounds - 1.83 pounds = 1.62 pounds
Therefore, Nina bought 1.62 pounds more walnuts than almonds.
