Answer:
The correct answer is less tan 45 %.
Step-by-step 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.
If we make a percentage: 19.7 : 65 = 0.30.
Barbara has ingested only 30% of the daily vitamins C that the body needs. In order to cover the necessary amount, she would have to eat more than one potato.
