Berries market (blueberries + strawberries)
Total berries = 1.0+5.0=6.0 million tons.
Sunny’s berry sales = 0.9+0.9=1.8 million tons.
Share = 1.8/6.0=0.30=30%.
At 30%, Sunny is well below the 60% or 90% thresholds — the court would not treat Sunny Valley as a monopolist in the berries market under the 90–60–30 rule.
