Ainsley is trying to eat more vitamins and minerals. She checks the nutrition labels on two different brands of soup. Brand A has 40 percent of the daily value of iron in a 2-cup serving. Brand B has 30 percent of the daily value of iron in a 1-cup serving. Ainsley plans to eat 3 cups of soup. Which brand will give her more iron?
1) Brand A has more iron in 3 cups of soup.
2) Brand A and B offer the same amount of iron.
3) It is not possible to tell which brand has more iron from the information given.
4) Brand B has more iron in 3 cups of soup.
The answer is not 4 although she would be getting more iron from that, so I am thinking it's 3?
I said that it wasn't 4 because I picked that answer and it was incorrect. Which makes no sense but, that what it says
I have this same question and it is saying that number 4 is incorrect. i'm so confused.
The answer is actually 1) Brand A has more iron in 3 cups of soup.
B has 40% in 2 cups, so 60% in 3 cups
B has 30% in one cup, so 90% in 3 cups
why do you say the answer is not #4, since she gets more iron there?
To determine which brand will give Ainsley more iron, we need to compare the total iron content in the soups. Let's calculate the iron content for each brand:
Brand A:
- Iron content per 2-cup serving: 40 percent of the daily value
- Since Ainsley plans to eat 3 cups of soup, we can calculate the iron content for 3 cups by multiplying the iron content per 2-cup serving by 1.5 (since 3 cups is 1.5 times the amount of a 2-cup serving):
Iron content in 3 cups of Brand A soup = 40% of the daily value * 1.5 = 60% of the daily value
Brand B:
- Iron content per 1-cup serving: 30 percent of the daily value
- Since Ainsley plans to eat 3 cups of soup, we can calculate the iron content for 3 cups by multiplying the iron content per 1-cup serving by 3:
Iron content in 3 cups of Brand B soup = 30% of the daily value * 3 = 90% of the daily value
Comparing the iron content in 3 cups of soup from both brands:
- Brand A has 60% of the daily value of iron.
- Brand B has 90% of the daily value of iron.
Therefore, the correct answer is: Brand B has more iron in 3 cups of soup. So the answer is not 3, but option 4.
