First, we will calculate the result of the addition in the parentheses:
(3,16 + 2,12) = 3.16 + 2.12 = 5.28
Next, we will calculate the result of the subtraction in the parentheses:
(0.934 - 0.81) = 0.124
Finally, we will multiply the result of the subtraction by 250:
0.124 * 250 = 31
Now, we will add the results of the addition and multiplication:
5.28 + 31 = 36.28
Therefore, the final answer is 36.28.
