To determine the correct number of significant figures in the final answer for the calculation (67.31 - 8.6 + 212.198), you first perform the subtraction and addition operations. The result of the subtraction (67.31 - 8.6) is 58.71, which has four significant figures. Adding 212.198 to 58.71 yields 270.908, which also has four significant figures. Therefore, the final answer should be rounded to four significant figures: 270.9.
