A base course requires 1,440 compacted tons. The estimator carries 3.5% waste and loss. How many tons should be ordered?
Correct Answer
B) 1,490 tons
Apply the waste and loss factor to required compacted tons.
Why This Is the Correct Answer
Apply the waste and loss factor to required compacted tons.
Why the Other Options Are Wrong
Option A: 1,389 tons
1,389 tons is below the supported result for imported stone; it likely omits allowance, conversion, coverage, or final round-up.
Option C: 1,440 tons
1,440 tons is below the supported result for imported stone; it likely omits allowance, conversion, coverage, or final round-up.
Option D: 1,520 tons
1,520 tons is above the supported result for imported stone; it likely double-counts allowance, uses the wrong unit, or rounds too early.
