In the shower replacement file, a stair trim run needs 22 pieces at $18 each. What material cost should be estimated?
Correct Answer
A) $396.
Twenty-two pieces at $18 each equals $396.
Why This Is the Correct Answer
Twenty-two pieces at $18 each equals $396.
Why the Other Options Are Wrong
Option B: $374 total.
$374 total. is below the supported result for trim cost calculation; it likely omits allowance, conversion, coverage, or final round-up.
Option C: $418 total.
$418 total. is above the supported result for trim cost calculation; it likely double-counts allowance, uses the wrong unit, or rounds too early.
Option D: $440 total.
$440 total. is above the supported result for trim cost calculation; it likely double-counts allowance, uses the wrong unit, or rounds too early.
