Final answer:
To find the better deal on shelled walnuts, compare the price per ounce at each store. Store A offers walnuts at $0.1998 per ounce, while Store B offers them at $0.1873 per ounce. Therefore, walnuts are a better deal at Store B.
Step-by-step explanation:
To determine which store offers a better deal on shelled walnuts, we need to compare the price per ounce at each store. At Store A, 60 ounces of shelled walnuts cost $11.99. To find the price per ounce at Store A, we divide the total cost by the number of ounces:
Store A Price Per Ounce = $11.99 / 60 ounces = $0.1998 per ounce
At Store B, a 4-pound bag at $11.99 needs to be converted to ounces since there are 16 ounces in one pound:
4 pounds = 4 x 16 ounces = 64 ounces
Store B Price Per Ounce = $11.99 / 64 ounces = $0.1873 per ounce
By comparing the two, we see that Store B's price per ounce is less than Store A's price per ounce, indicating that Store B offers the better deal on shelled walnuts.
