Final answer:
The inedible yield percentage for avocados, if the edible yield is 75%, is 25%. This is calculated by subtracting the edible yield percentage from 100%.
Step-by-step explanation:
If the edible yield percentage for avocados is 75%, then we can calculate the inedible yield percentage by subtracting the edible yield percentage from 100%. Therefore, the inedible yield percentage would be 100% - 75%, which equals 25%.
In the context of yield, the term percent yield usually refers to the efficiency of a process. For example, if a chemical reaction has a percent yield of 72%, it means that 72% of the theoretical amount was actually produced. In the case of food products like avocados, the yield can also refer to the amount of the food that is usable for consumption after removing inedible parts.
Since the edible portion is 75%, it leaves the remainder for the inedible portion. Hence, option 1) 25% is the correct answer to the question of what the percentage of inedible yield is.
