Answer
$60.6\%$
Work Step by Step
Total fruit =
1.0+5.0+10.0=16.0 million tons.
Sunny’s total = 0.9+0.9+7.9=9.7 million tons.
Share = 9.7/16.0=0.60625≈60.6%.
A share of ≈60.6% sits at the 60% threshold in the 90–60–30 rule. That is high concentration — courts using that heuristic would typically view the firm as having monopoly power or being dominant in the all-fruit market (it’s essentially at/just above the 60% cutoff). Whether a court formally labels it a “monopolist” could depend on additional evidence, but under the rule-of-thumb the firm would be treated as highly dominant.
