To determine how many grams of protein Luisa consumed from 3 ounces of pretzels, we would typically need to know the protein content of pretzels per ounce.
On average, pretzels contain about 2g of protein per ounce.
So, for 3 ounces of pretzels:
\[ 3 \text{ ounces} \times 2 \text{ g protein/ounce} = 6 \text{ g protein} \]
Given the provided options, none seem to match, which suggests a miscalculation or misunderstanding in the expected protein content of pretzels or the values given in the responses.
Please check the protein content of the pretzels you have or provide more detail for an accurate response.
