Explanation:

Step1: Select sample foods & their vitamin D %

Assume 3 foods:

1. Salmon (3 oz): 100% of daily value (DV)
2. Fortified milk (1 cup): 25% of DV
3. Egg yolk (1 large): 6% of DV

Step2: Sum the percentages

$\text{Total} = 100\% + 25\% + 6\%$

Step3: Calculate total intake percentage

$\text{Total} = 131\%$
(Note: This uses a 19-50 year old's 600 IU DV as reference)

Answer:

Foods Eaten & Vitamin D Percentage:

1. Salmon (3 oz): 100%
2. Fortified milk (1 cup): 25%
3. Large egg yolk: 6%

Total Percentage of Vitamin D:

131% of recommended daily intake
