Insufficient information to determine current number of supervisors Steps:

• Current production requires 110 units × 4 hours/unit = 440 labor hours.
• Labor hours per operator = 36, so operators needed = 440 ÷ 36 ≈ 12.22 (at least 13 for integer operators).
• Supervisors needed = ceil(12.22 ÷ 10) = 2 minimum.
• Exact number of supervisors not given; could be 2 or more, so maximum production without extra supervisor (2×10×36÷4=180 or higher) cannot be calculated precisely.

Why B is correct:

• Problem lacks details on current supervisors, making all options indeterminate.

Why the others are wrong:

• A: Irrelevant small number; no basis in calculations.
• C: Approximates spare capacity (e.g., ~70–75 additional units with 2 supervisors) but assumes unstated details.
• D: Matches 10 operators' output (90 units) but ignores current 110-unit production requiring >10 operators.

Not enough information. Final answer: Not enough information.
