Final answer:
A single serving of the cereal provides 2% of the Recommended Daily Intake (RDI) for calcium, which is equal to 20 milligrams.
Step-by-step explanation:
The Recommended Daily Intake (RDI) of calcium for adults is 1,000 mg per day. A serving of the cereal provides 2% of the RDI for calcium. To find the actual amount of calcium this equals, multiply the total RDI by 0.02 (which is the same as 2%).
Calcium content calculation:
- Total RDI for Calcium = 1,000 mg
- Percentage provided by cereal = 2%
- Actual Calcium content = Total RDI * (Percentage / 100)
- Actual Calcium content = 1,000 mg * (2 / 100)
- Actual Calcium content = 20 mg
Therefore, a single serving of the cereal provides a person with 20 milligrams of calcium, which is 2% of the total recommended daily intake for an adult.
