The expanded form of 285 can be broken down based on the place values of each digit.
- The digit 2 is in the hundred's place, which represents \(2 \times 100\).
- The digit 8 is in the ten's place, which represents \(8 \times 10\).
- The digit 5 is in the one's place, which represents \(5 \times 1\).
So the correct expanded form for 285 is:
\((2 \times 100) + (8 \times 10) + (5 \times 1)\)
Thus, the correct answer is C. (2 x 100) + (8 x 10) + (5 x 1).
