Jada's usual dietary pattern provides 1,900 kcal and 75 grams of protein. What percentage of her total calories is from protein?

Question

The question asks what percentage of Jada's total daily calories come from protein, given 1,900 kcal total and 75 g protein.
First, convert protein grams to calories: protein has 4 kcal per gram, so 75 g × 4 kcal/g = 300 kcal from protein.
Next, compute the protein percentage of total calories: 300 kcal protein ÷ 1,900 kcal total ≈ 0.1579, which is about 15.8%.
Now evaluate each option:
Option 1: 16% — This matches the calculated value when rounded to the nearest whole percent, so it is correct.
Option 2: 27% — This would imply 0.27 × 1,900 ≈ 513 kcal from protein, far higher than the actual 300 kcal, so incorrect.
Option 3: 59% — This would require about 1,121 kcal from protein, which is not plausible given the data; clearly incorrect.
Option 4: 12% — This would correspond to 0.12 × 1,900 = 228 kcal from protein, which underestimates the actual 300 kcal, so incorrect.
Option 5: 36% — This would imply about 684 kcal from protein, again not matching the given 300 kcal, so incorrect.
In summary, only the 16% option aligns with converting 75 g of protein to calories and comparing to a 1,900 kcal total. The other choices misestimate the protein contribution or misapply the calorie-per-gram conversion.
