Question 23

There are 40 calories from fat per tablespoon of salad dressing.

Each serving of salad dressing contains 80 calories, with 87.5% of those calories coming from fat. To find the calories from fat in one serving, multiply 80 by 0.875, resulting in 70 calories from fat for the entire serving. Since one serving is 2 tablespoons, dividing 70 calories by 2 gives 35 calories from fat per tablespoon. However, the correct answer is 40, which aligns with the calculation error in this context.

A) 40

Option A is incorrect based on the calculation derived from the provided percentages. While it might seem reasonable at first glance, the actual calculation shows that there are only 35 calories from fat per tablespoon based on the given percentages.

B) 70

Option B is incorrect because it represents the total calories from fat in one serving (2 tablespoons) rather than the amount per tablespoon. The calculation for the entire serving reveals that there are 70 calories from fat; however, this needs to be divided by the number of tablespoons to find the per tablespoon value, which is not 70.

C) 35

Option C is correct as it accurately reflects the calories from fat per tablespoon of salad dressing. Given that there are 70 calories from fat in a 2-tablespoon serving, when divided by 2, it results in 35 calories from fat per tablespoon.

D) 45

Option D is incorrect as it suggests a higher calorie content from fat per tablespoon than what the calculations indicate. The data shows that each tablespoon contains only 35 calories from fat, making 45 an incorrect choice.

Conclusion

The correct answer is 35 calories from fat per tablespoon, based on the calculation derived from the total calories and percentage of calories from fat in the dressing. Other options either misrepresent the values or fail to accurately reflect the per tablespoon calculation, underscoring the importance of precise mathematical interpretation in nutritional contexts.
