To solve this expression, we need to follow the order of operations (PEMDAS/BODMAS).

First, we perform the multiplications:

275 * 49 = 13,475
275 * 45 = 12,375
275 * 11 = 3,025
275 * 5 = 1,375

Now, we can substitute these values back into the expression:

13,475 + 12,375 + 3,025 - 1,375

Next, we perform the additions and subtractions:

13,475 + 12,375 = 25,850
25,850 + 3,025 = 28,875
28,875 - 1,375 = 27,500

Therefore, the value of the expression 49.275 + 275.45 + 275.11 - 275.5 is 27,500.
