Answer:
25 silk leaves
Step-by-step explanation:
The opportunity cost would be what was normally stopped by doing something else, we have two scenarios:
First stage:
A combination of 60 silk roses and 80 silk leaves
Second stage:
A combination of 70 silk roses and 55 silk leaves
Therefore, comparing the two scenarios, by producing more silk roses, the amount of silk leaves is decreased, by the following amount:
80 silk leaves - 55 silk leaves = 25 silk leaves.
Therefore the opportunity cost is 25 silk leaves
