Adding all the numbers, we get 634.4. The answer should be rounded to the tenths place, which is why we choose option C. When adding decimals, it is important to keep the columns aligned. Adding the digits in the tenths column, we get 0.1+8.7=8.8. Carrying the 1 to the ones column, we get 9+4+6+7=26. Finally, adding the digits in the hundreds column, we get 5. Therefore, the answer is 634.4.
