To determine how many grams of protein Luisa consumed from 3 ounces of pretzels, we need to know the protein content of pretzels. On average, pretzels contain about 2.5 grams of protein per ounce.
Calculating the protein for 3 ounces:
\[ \text{Protein} = 3 , \text{ounces} \times 2.5 , \text{grams/ounce} = 7.5 , \text{grams} \]
Since 7.5 grams is not an option among your responses, it seems there may be a rounding issue or a misunderstanding. The closest answer available to 7.5 grams is 7.79 grams.
So, the best response would be 7.79 g.
