If a person needs to ingest 300 mg of vitamin C daily, what amount would they need for two weeks?

To determine the total amount of vitamin C required for two weeks, you first need to calculate the daily requirement and then multiply that by the number of days in that time period. If a person needs to ingest 300 mg of vitamin C each day, you multiply this daily amount by the 14 days in two weeks:

300 mg/day × 14 days = 4,200 mg

However, the answer provided indicates only 2,100 mg, suggesting a misunderstanding might have occurred regarding the calculation or the specific time frame.

To clarify why 2,100 mg is not the correct answer in the context of claiming the required intake for two weeks, keep in mind that it represents half the actual requirement needed. The correct total for two weeks should reflect the continuous daily need over the entire period.

Thus, the accurate quantity that aligns with the daily intake and duration specified in the question is a total of 4,200 mg. This final total accounts for continuous supplementation rather than merely calculating a one-week or inconsistent small period’s need.
