Question

Please help me and my daughter... never seen anything like this LOL

Answer 1

Given the details in the table, we can solve the questions using the following steps:

Part A: Percent daily value of fat calories for each of the four foods. Recall that there are 9 calories per gram of fat.

For one bowl of cereal and milk:

`\begin{gathered} calories\text{ for the food above is:} \\ 9*6=45\text{ calories} \\ To\text{ get the percent daily value of fat calories=} \\ (45)/(363)*100=12.3967 \\ \approx12\text{ \%} \end{gathered}`

For One peanut butter and Jelly Sandwich:

`\begin{gathered} calories\text{ in }8\text{ grams }of\text{ the food above is:} \\ 9*8=72 \\ To\text{ get the percent daily value of fat calories=} \\ (72)/(196)*100=36.735 \\ \approx37\text{ \%} \end{gathered}`

For One Waffle:

`\begin{gathered} calories\text{ in 11 grams }of\text{ the food above is:} \\ 9*11=99 \\ To\text{ get the percent daily value of fat calories=} \\ (99)/(205)*100=48.293 \\ \approx48\text{ \%} \end{gathered}`

For One granola bar:

`\begin{gathered} calories\text{ in 6 grams }of\text{ the food above is:} \\ 9*6=54 \\ To\text{ get the percent daily value of fat calories=} \\ (54)/(130)*100=41.538 \\ \approx41\text{ \%} \end{gathered}`

PART B: Based on the percent daily values of fat calories gotten for the four foods above, it can be said that the least healthy food is One Waffle with 48% while the most healthy food is One Bowl of Cereal and Milk with 12%.

PART C: The most healthy food was One Bowl of Cereal and Milk while the least healthy is One Waffle because The Institute of Medicine and the American Heart Association recommend a total fat intake of 25-35 percent of calories. Hence, the higher the food goes above the 35% mark, the less healthy the food becomes.
