I would start by breaking apart the 275 into 200, 70, and 5. Then I
would multiply 4 by each of those numbers, giving you 800, 280, and 20.
Then, I would add those number back together (800+280+20) and that gives
you a final answer of 1,100. 

The expression  that can be used would be...
4(200)+4(70)+4(5)
