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 iron on the nutrition label to calculate its % of dv, b.
use the iron amount on the nutrition label to calculate the %dv for iron.
nutrient sodium vitamin d iron
dv 2300mg 20mcg 15mg
%dv 80mg ≈ 0.0348 ≈ 3% 0mcg = 0 = 0% 20mcg b =
(round to the nearest whole percent as needed.)
the percent column on the label shows the percent values based on a 2000 - calorie diet. nutrition facts

*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 %DV formula

The formula for calculating the % Daily Value (%DV) is $\%DV=\frac{\text{Amount in serving}}{\text{DV}}\times100$.

Step2: Identify values for iron

The amount of iron in the serving is $1.0$ mg and the DV for iron is $15$ mg.

Step3: Calculate %DV for iron

Substitute the values into the formula: $\%DV=\frac{1.0}{15}\times 100=\frac{100}{15}\approx 7\%$.

Answer:

$7$%
