What is the sum of all possible 3-digit numbers that can be constructed using the digits 2, 3, and 5 if each digit can be used only once in each number?	Choose the correct choice from the following.
A) 2210	B) 2220	C) 2230	D) 2240	E) 2250
There are 6 possible arrangements of the three numbers.   Then each number will be in the hundreds, tens, and ones place two times each.   The sum is 2(222) + 2(333) + 2(555) = 2220   The answer is 2220.
