A firm is about to undertake the manufacturing of a product, and is weighing three capacity alternatives: small job shop, large job shop, and repetitive manufacturing plant. The small job shop has fixed costs of $3,000 per month, and variable costs of $10 per unit. The larger job shop has fixed costs of $12,000 per month and variable costs of $4 per unit. The repetitive manufacturing plant has fixed costs of $24,000 and variable costs of $2 per unit.
