To determine how many grams of protein Luisa consumed from eating 3 ounces of pretzels, we need to know the typical protein content in pretzels.
On average, pretzels contain about 1-2 grams of protein per ounce. Let's assume an average of 2 grams of protein per ounce for calculation purposes.
Calculating the protein:
3 ounces of pretzels x 2 grams of protein per ounce = 6 grams of protein.
Given the options:
- 77.79 g
- 7.79 g
- 87.79 g
- 8.79 g
None of these options are 6 grams, which suggests the assumption or average protein content we used might not correspond with the pretzels in question. However, based on the provided options, the closest lower option would be:
7.79 g.
Therefore, the likely answer is 7.79 g.
