Final answer:
One serving of the food provides 10% of the daily value of protein.
Step-by-step explanation:
To find the percent of the daily value of protein provided by one serving of the food, we need to calculate the percentage of protein per serving in relation to the daily value of protein. The average person needs 50 grams of protein each day. If one serving of the food provides 5 grams of protein, we can calculate the percentage as follows:
(5 grams of protein / 50 grams of protein) x 100 = 10%
Therefore, one serving of the food provides 10% of the daily value of protein.
