For 750 square feet of work at a productivity factor of 0.24 labor-hours per square foot, how many labor-hours are needed?
Correct Answer
A) 180 labor-hours.
Seven hundred fifty square feet times 0.24 labor-hours per square foot equals 180 labor-hours.

Seven hundred fifty square feet times 0.24 labor-hours per square foot equals 180 labor-hours.
Why the Other Options Are Wrong

Option D: 220 labor-hours.
220 labor-hours. is above the supported result for productivity calculation; it likely pays the wrong premium tier or counts the same hours twice.
