The insulation takeoff covers 725 square feet at $2.10 per square foot. What material cost is estimated before waste?
Correct Answer
C) $1,522.50.
The cost is 725 x $2.10 = $1,522.50.
Why This Is the Correct Answer
The cost is 725 x $2.10 = $1,522.50.
Why the Other Options Are Wrong

Option B: $1,500 total.
$1,500 total. is below the supported result for insulation cost calculation; it likely omits allowance, conversion, coverage, or final round-up.
Option D: $1,595 total.
$1,595 total. is above the supported result for insulation cost calculation; it likely double-counts allowance, uses the wrong unit, or rounds too early.
