Explanation:
From the question we are told that
The number of milk drinkers considered is
![m = 100](https://img.qammunity.org/2021/formulas/mathematics/high-school/pdzm60t1jr5ltp5an8xaquhj8np7y58u0j.png)
The number of skim milk drinkers
![n = 50](https://img.qammunity.org/2021/formulas/mathematics/college/qc5c7kyldiu6disabve390wa33rhuzdpxd.png)
The gallons of milk supplied is q = 23 gallons
Generally the proportion of skim milk drinkers is mathematically represented as
![p = (n)/(m)](https://img.qammunity.org/2021/formulas/mathematics/college/lassb6ypb5is6q4qnm872q08edm16r8zlr.png)
![p = 0.5](https://img.qammunity.org/2021/formulas/mathematics/college/ytflwpu4bmyp7aexf6kq0asuwzv2jwe2ob.png)
Generally the gallons of milk order that is skim milk is mathematically represented as
![s = 0.5 * 23](https://img.qammunity.org/2021/formulas/mathematics/college/7y4ncjojcxzyo0ymco0uekbs7bj5n1q359.png)
=>
![s = 12 \ gallons](https://img.qammunity.org/2021/formulas/mathematics/college/sb612tyhhyv8true3ia66o87bazpu37bnt.png)
