By eating her potato, is Barbara taking in less than 45%
of her daily Vitamin C, more than 50% of her daily
Vitamin C, or exactly 45% of her Vitamin C?

The correct answer is less tan 45 %.

Explanation:

If Barbara is only eating one potato, then she is ingesting about 19.7 mg of vitamin C. The amount of vitamin C that an adult's body needs is between 65 to 90 mg daily.
