To calculate the amount of protein Luisa consumed from 3 ounces of pretzels, we first determine the protein in 1 ounce and then multiply by 3.
The protein content in 1 ounce of pretzels is 2.93 g.
Now, for 3 ounces:
\[ \text{Protein in 3 ounces} = 2.93 , \text{g/oz} \times 3 , \text{oz} = 8.79 , \text{g} \]
Thus, Luisa consumed 8.79 g of protein.
The correct response is:
8.79 g.
