Answer: $1000
Step-by-step explanation:
Annual demand (D) = 8000
Cost per order (S) = $1000
Cost per unit to print = $8 per book
Storage cost = $2 per book per year
The minimum total cost can be found thus :
√(2 × D × S) / storage cost * cost per unit
√(2 × 8000 × 1000) / (2 * 8)
√ (16,000,000 / 16
√ (1,000,000
= 1000
Hence , minimum total cost $1000
