15.00
18.40
16.58
12.25

The correct answer is: 16.58

To evaluate the expression 15 × 1.5 - 0.2 × 30.1 + 0.0625 × 0.625, we should perform the calculations step by step following the order of operations: 1. First, calculate 15 × 1.5: \[ 15 \times 1.5 = 22.5 \] 2. Next, calculate 0.2 × 30.1: \[ 0.2 \times 30.1 = 6.02 \] 3. Then calculate 0.0625 × 0.625: \[ 0.0625 \times 0.625 = 0.0390625 \] 4. Now, substitute these values back into the expression: \[ 22.5 - 6.02 + 0.0390625 \] 5. Perform the subtraction: \[ 22.5 - 6.02 = 16.48 \] 6. Now, add 0.0390625: \[ 16.48 + 0.039062
