A crew must install 1,500 square feet of flooring at a production rate of 50 square feet per labor-hour. What is the MINIMUM total labor-hours the estimate should include for this task?

Labor-hours = area divided by production rate = 1,500 / 50 = 30 labor-hours. This is total effort regardless of crew size; a 2-worker crew would finish in about 15 clock hours, but the labor-hour count is still 30. Option a confuses clock hours with labor-hours. Options c and d misapply the rate. Divide the quantity by the output per labor-hour to size the labor line.
