A large organic nursery has somewhere between 3 and 6 (inclusive) garden plots of herbs when it closes for the season in the fall. In each plot there are between 20 and 30 (inclusive) rosemary plants. If, typically, 10% of those plants don’t winter over successfully until spring, what would be the largest number of plants that could be lost during the winter?
The maximum number of rosemary plants would be 6 · 30 = 180. If 10% of those plants are lost, then 18 plants would be affected.
