Answer: 14 ounces of flour
Explanation:
We can set up a proportion to solve this problem using ratios.
The ratio of muffins to flour is 25:35, or simplified, 5:7. So for every 5 muffins, we need 7 ounces of flour.
Now we can multiply the ratio by 2, to get 10 muffins and the respective ounces of flour required.
5 : 7
x2 x2
10 : 14
So, we get the ratio 10:14.
So, for every 10 muffins, we need 14 ounces of flour.
