Eight hundred forty square feet times 0.16 labor-hours per square foot equals 134.4 labor-hours.

Answer Options
A
134.4 labor-hours.
B
120 labor-hours.
C
148 labor-hours.
D
168 labor-hours.

Why This Is the Correct Answer

Eight hundred forty square feet times 0.16 labor-hours per square foot equals 134.4 labor-hours.

Why the Other Options Are Wrong

Option B: 120 labor-hours.

120 labor-hours. is below the supported result for productivity calculation; it likely skips a premium-pay or employer-cost component.

Option C: 148 labor-hours.

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

Option D: 168 labor-hours.

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

Memory Technique

Checking Production payroll: time, premium, reimbursement, proof in separate buckets.
