Determine the length of cotton left.
This is calculated by subtracting the length sold from the total length of cotton.
![Length\ Left = Total - Length\ Sold](https://img.qammunity.org/2021/formulas/mathematics/college/xnm8kpeva8j5oa8j16hkdr7jz4aoaimbe5.png)
Substitute values for Total length and length sold
![Length\ Left = 24.75m - 9.85m](https://img.qammunity.org/2021/formulas/mathematics/college/44qicobo9ulbgh7tjttnli23zwvkg8funn.png)
![Length\ Left = 14.9m](https://img.qammunity.org/2021/formulas/mathematics/college/9a5lx715jwl969ips52oksp5rd03zexho4.png)
Hence, there are 14.9 meters of cotton left.
