When rounding a number to the nearest hundred, you look at the digit in the hundreds place. In this case, the hundreds digit is 1. Since the digit to the right of it (in the tens place) is 5 or greater, you would round up the hundreds digit to the next hundred. Therefore, 3150 rounded to the nearest hundred is 3200.
