1. The problem asks to solve the addition of two decimal numbers: $$94.852 + 4.007 = n$$. 2. The formula for addition is straightforward: add the numbers digit by digit, aligning the decimal points. 3. Align the numbers: $$\begin{array}{r} 94.852 \\ +\ 4.007 \\ \hline \end{array}$$ 4. Add each column starting from the right: $$2 + 7 = 9$$ $$5 + 0 = 5$$ $$8 + 0 = 8$$ $$4 + 4 = 8$$ $$9 + \cancel{\text{(no digit)}} = 9$$ 5. So the sum is: $$94.852 + 4.007 = 98.859$$ 6. The answer is exactly $98.859$ without rounding. 7. Among the options, the correct one is $98.859$.
