Question

3 for the three - part question that follows, provide your answer to each question in the given workspace. identify each part with a coordinating response. be sure to clearly label each part of your response as part a, part b, and part c. use the table below to answer questions in part a, part b, and part c.
food/serving size\tone bowl of cereal and milk\tone peanut butter and jelly sandwich\tone waffle\tone granola bar
total calories per serving\t363 calories\t196 calories\t205 calories\t130 calories
grams of fat per serving\t6 grams\t8 grams\t11 grams\t6 grams
part a: find the percent daily value of fat calories for each of the four foods. round to the nearest whole percent. note: there are 9 calories per gram of fat.
part b: which food item is the least healthy and most healthy based on percent daily value for fat calories?
part c: explain your rationale to part b using a complete sentence.

Explanation:

Step1: Calculate fat - calorie percentage for each food

The formula to calculate the percent of fat calories is $\text{Percent of Fat Calories}=\frac{\text{Grams of Fat}\times9}{\text{Total Calories}}\times100$.
For one granola bar: $\frac{6\times9}{130}\times100=\frac{54}{130}\times100\approx 41.54\%$.
For one waffle: $\frac{11\times9}{205}\times100=\frac{99}{205}\times100\approx 48.29\%$.
For one peanut - butter and jelly sandwich: $\frac{8\times9}{196}\times100=\frac{72}{196}\times100\approx 36.73\%$.
For one bowl of cereal and milk: $\frac{6\times9}{363}\times100=\frac{54}{363}\times100\approx 14.88\%$.

Step2: Round to the nearest whole percent

One granola bar: $42\%$.
One waffle: $48\%$.
One peanut - butter and jelly sandwich: $37\%$.
One bowl of cereal and milk: $15\%$.

Step3: Determine least and most healthy

Lower percent of fat calories is generally considered healthier. So the most healthy is the bowl of cereal and milk with $15\%$ fat - calorie percentage, and the least healthy is the waffle with $48\%$ fat - calorie percentage.

Step4: Explain rationale for Part B

Foods with a lower percentage of fat calories are considered healthier in terms of fat content. The bowl of cereal and milk has the lowest percentage of fat calories among the four foods, while the waffle has the highest.

Answer:

Part A: One granola bar: $42\%$, One waffle: $48\%$, One peanut - butter and jelly sandwich: $37\%$, One bowl of cereal and milk: $15\%$.
Part B: The least healthy is the waffle and the most healthy is the bowl of cereal and milk because the waffle has the highest percentage of fat calories ($48\%$) and the bowl of cereal and milk has the lowest ($15\%$).
Part C: As explained above, lower fat - calorie percentages are generally associated with healthier food choices in terms of fat content.
