Explanation
Divide $6,450 by $85 to get 75.88… But don’t just round up!
Each person gave at least $85.
If 76 people attended and each gave the minimum of $85, then $6,460 would have been collected.
Since only $6,450 was collected, that 76th person could not have attended. Instead, round down to 75. (This means at least one person gave more than the minimum.)
Hence option C is correct!
