Please help me on this. ​

A dozen is 12, and so 2.5 dozen is 30, so 30 muffins require 1.25 cups of flour, so it should be 5 cups of flour for 10 dozen muffins.

Its would be 5 cups of flour.
Explanation: The ratio is 2.5/1.25 and you’re trying to find 10/x First you divide 10 to 2.5 which equals 4, then use to the 4 and multiply 1.25 and you get 5. Aka x. I hope this explanation helped :))

Basic algebra equation. first set up your equation: divide out 9.and now you are left with 2x + 4 = 8.
