ExplanationThis is a maximization question. To solve maximization questions, you often have to minimize something else. In order to find the maximum number of donors, minimize the donation per person. In this case, everyone could pay exactly $14:
\(\frac{237}{14} = 16.92\)
Rounding up to 17 is not right, because it is not possible that 17 people donated $14 each (the total contributions would be $238, which is greater than $237).
The answer is (D), or 16.
