Question

a partial table of nutrients and daily values (dvs) based on a 2000 - calorie diet is provided. the sodium row and the vitamin d row are completed, and each % of the dv is calculated. compare each amount with the amount on the given nutrition label. now use the amount of saturated fat on the nutrition label to calculate its % of dv, x.
use the saturated fat amount on the nutrition label to calculate the %dv for saturated fat.
nutrient dv
sodium 2300mg
vitamin d 20mcg
saturated fat 16g
%dv
80mg ≈ 0.0348 ≈ 3%
2300mg
0mcg - 0 = 0%
20mcg
x =
(round to the nearest whole percent as needed.)
the percent column on the label shows the percent daily values based on a 2000 - calorie diet.

*the % daily value (dv) tells you how much of a nutrient in a serving of food contributes to a daily diet. 2,000 calories a day is used for general nutrition advice.

Explanation:

Step1: Recall the formula for %DV

The formula for calculating the % Daily Value (%DV) of a nutrient is $\%DV=\frac{\text{Amount in serving}}{\text{Total daily amount}}\times100$. For saturated - fat, the total daily amount of saturated fat for a 2000 - calorie diet is 20g (a common reference value). The amount of saturated fat in the serving is 16g.

Step2: Substitute values into the formula

Substitute the amount of saturated fat in the serving ($a = 16$g) and the total daily amount ($t=20$g) into the formula: $\%DV=\frac{16}{20}\times100$.

Step3: Calculate the result

First, $\frac{16}{20}=0.8$, then $0.8\times100 = 80$.

Answer:

80%
