you must type your data (numbers only, no commas) into the blank spaces for questions a, b, and c before you respond to questions d, e, and f. responses to questions e and f will appear after you have entered your data from the bar graph report. be sure to use your data, not the data from the sample report.
a enter your saturated fat intake: 4.16 grams of saturated fat
b multiply grams of saturated fat by 9 kcal/g 37.40 kcal from saturated fat
c enter your total calorie intake: 889 total kcal
note remember that calorie (with a capital c) = kilocalorie.
d according to the dietary guidelines, americans should consume less than of calories from saturated fat
5%
10%
25%
50%
e what percentage of your total kilocalories came from saturated fat?
0.5%
1.9%
3.3%
4.2%
f. was your actual saturated fat intake (as a percentage of total kcal) below the limit suggested by the dietary guidelines?
no
yes

Explanation:

Step1: Recall dietary guideline

According to the Dietary Guidelines, Americans should consume less than 10% of calories from saturated fat. So the answer to d is 10%.

Step2: Calculate percentage of saturated - fat calories

The formula for calculating the percentage of total kilocalories from saturated fat is $\frac{\text{kcal from saturated fat}}{\text{total kcal}}\times100\%$. Given that kcal from saturated fat is 37.40 and total kcal is 889. So the percentage is $\frac{37.40}{889}\times 100\%\approx4.2\%$.

Step3: Compare with the limit

Since 4.2% < 10%, the actual saturated - fat intake (as a percentage of total kcal) is below the limit suggested by the Dietary Guidelines.

Answer:

d. 10%
e. 4.2%
f. YES
