The correct answer is
$128.218$

The problem requires calculating the precise value of the expression \(160.342 - 32.124\) and checking against the given options to identify the correct answer.

  1. Start by aligning the numbers for subtraction:
160.342
- 32.124
______
  1. Subtract columns starting from the rightmost (hundredths place):
    • 2 - 4: Since you cannot subtract 4 from 2, borrow 1 from the tenths place:
      • 12 (after borrowing) - 4 = 8
    • Tenths place adjustment: 3 becomes 2 (after borrowing), so 2 - 2 = 0
    • Ones place: 0 - 1; Borrow from the tens place (5 becomes 4):
      • 10 - 1 = 9
    • Tens place: 4 - 2 = 2
    • Hundreds place: 6 - 3 = 3
    • Thousands place: 1 - 0 = 1
  2. The result of the subtraction is:
128.218
  1. Verify by checking against the provided options to find an exact match. The correct answer is \(128.218\), which matches the given correct option.

Hence, the answer is 128.218.
