To determine how much more efficient organic farming is compared to regular farming, we need to follow these steps:
1. Identify the efficiency percentages for both types of farming:
- Organic farming has an efficiency of 75%.
- Regular farming has an efficiency of 65%.
2. Calculate the difference in efficiency between organic farming and regular farming:
[tex]\[
\text{Efficiency Difference} = \text{Efficiency of Organic Farming} - \text{Efficiency of Regular Farming}
\][/tex]
Substituting the given values:
[tex]\[
\text{Efficiency Difference} = 75\% - 65\%
\][/tex]
3. Perform the subtraction:
[tex]\[
75\% - 65\% = 10\%
\][/tex]
Therefore, organic farming is 10% more efficient than regular farming.
The correct answer is:
10%.
