800 + 70 + 1 + 0.5 + 0.07 + 0.004 Which of the following is equivalent to the expression above? A. 871.754 B. 871.574 C. 817.574 D. 8,710.754

Answer 1

To simplify the expression $800+70+1+0.5+0.07+0.004$, we can add the numbers step by step:

1. Add $800$ and $70$: $$800+70=870$$

2. Add $1$: $$870+1=871$$

3. Add $0.5$: $$871+0.5=871.5$$

4. Add $0.07$: $$871.5+0.07=871.57$$

5. Finally, add $0.004$: $$871.57+0.004=871.574$$

So, the final result is $871.574$.

Among the options provided, the equivalent expression is:

B. 871.574
