A sheathing crew can install 450 sf per day. The bid quantity is 3,600 sf and the crew cost is $2,240 per day. What labor cost should be carried?
Correct Answer
C) $17,920
Divide the quantity by daily production, then multiply by the crew-day cost.
Why This Is the Correct Answer
Divide the quantity by daily production, then multiply by the crew-day cost.
Why the Other Options Are Wrong
Option A: $16,800
$16,800 is below the supported result for labor productivity; it likely omits allowance, conversion, coverage, or final round-up.
Option B: $18,670
$18,670 is above the supported result for labor productivity; it likely double-counts allowance, uses the wrong unit, or rounds too early.
Option D: $20,160
$20,160 is above the supported result for labor productivity; it likely double-counts allowance, uses the wrong unit, or rounds too early.
