D. 60

Answer

To solve the expression \( 35 \times 2 + 20 - 10 \), we will follow the order of operations, which is multiplication first, then addition and subtraction.

### Step-by-Step Solution:

1. **Multiply** \( 35 \) by \( 2 \):
\[ 35 \times 2 = 70 \]

2. **Add** \( 20 \) to the result from step 1:
\[ 70 + 20 = 90 \]

3. **Subtract** \( 10 \) from the result in step 2:
\[ 90 - 10 = 80 \]

Thus, the final value of the expression \( 35 \times 2 + 20 - 10 \) is \( 80 \).
