To determine how many grams of protein Luisa consumed from 3 ounces of pretzels, we can use the information provided:
1 ounce of pretzels contains 8.79 grams of protein.
If Luisa ate 3 ounces: \[ 3 , \text{oz} \times 8.79 , \text{g/oz} = 26.37 , \text{g of protein} \]
However, it seems that you provided multiple choice answers which do not include 26.37 g, indicating a misunderstanding or an error in the presented options.
Based on a standard approach, if we recalculate based on typical information about pretzels, none of the responses provided (87.79 g, 8.79 g, 77.79 g, and 7.79 g) accurately reflect Luisa's protein intake.
Given the choices, it seems that the best approach would be to consider the amount of protein in 1 ounce and look at the choices for a closer approximation.
Based on the protein per each ounce (8.79 grams), the total for 3 ounces would still be 26.37 grams, which does not match any of the options provided.
Ensure the nutritional information matches a typical source for pretzels or specify further to clarify!
