Answer:
8 pounds
Step-by-step explanation:
The computation of economic order quantity is
EOQ = √ 2 × Annual demand × Ordering cost / Carrying cost
Where;
Annual demand = 52 weeks × 4 pounds = 208 pounds
Ordering cost = $8
Carrying cost = $1 per pound per week × 52 = $52
EOQ = √ 2 × 208 × $8 / $52
EOQ = 8 pounds
Therefore, Grounds should order 8 pounds at a time.
