To calculate how many grams of protein Luisa consumed, we'll first need to determine how many calories of pretzels she ate and then convert that to protein.
-
Calculate the protein per ounce:
- There are 28.35 grams in one ounce. With the nutritional facts provided per serving (presumably per ounce or another serving size), we need to ensure we use the correct ratio.
- From the provided data, we can first calculate the grams of protein in an ounce if 108 calories correspond to a certain serving size (which is assumed here as 1 ounce or 28.35 g for calculation).
-
Calculate total protein consumed in 3 ounces:
- Protein in 1 ounce of pretzels = 2.93 g
- Therefore, for 3 ounces, the total protein would be: \[ \text{Total protein} = 2.93 \text{ g/ounce} \times 3 \text{ ounces} = 8.79 \text{ g} \]
So, the correct answer is 8.79 g.
