((3,2+0,32):0,1-(50-7,2)•0,1)•100

To solve this expression, follow the order of operations (PEMDAS/BODMAS):

1. Calculate inside the innermost parentheses first: (50 - 7.2) = 42.8

2. Calculate the expression inside the outer parentheses: (3, 2 + 0.32):0,1- 42.8 • 0,1 (3.52):0.1 - 42.8 • 0.1

3. Perform division first: (3.52) / 0.1 = 35.2

4. Now, perform multiplication: 35.2 - 42.8 • 0.1 35.2 - 4.28

5. Subtract: 35.2 - 4.28 = 30.92

6. Finally, multiply by 100: 30.92 • 100 = 3092

Therefore, the final result of the given expression is 3092.
