To find out how many cups of blueberries Marco will need if he has 2 cups of flour, we can look at the given ratios between cups of flour and cups of blueberries.
We can write down the ratios based on the table:
- For 3/4 cup of flour, there are 1/4 cup of blueberries.
- For 1 cup of flour, there are 1/2 cup of blueberries.
- For 1 1/2 cups of flour, there are 3/4 cup of blueberries.
- For 2 cups of flour, there are 7/8 cup of blueberries.
- For 2 1/4 cups of flour, we can find the ratio to blueberries, and so on.
From the table, when Marco uses 2 cups of flour, the corresponding amount of blueberries is 7/8 cup.
Therefore, if Marco has 2 cups of flour, he will need:
7/8 cup of blueberries.
None of the options provided match 7/8 cup, but since the answer is not provided in the options, it seems there might be a mismatch in the question and the choices.
If you're looking for the best related answer (though not exact from what you've given), it would be B. 2/3 cup, since it's less than the required 7/8 cup.
