Solutions

Expert Solution

Annual sale, A = 4,000,000
Carrying cost per zen-zen, C = $0.02
Ordering cost per order, O = $501

Answer 1.

Number of orders per year = 36

Order size = Annual sale / Number of orders per year
Order size = 4,000,000 / 36
Order size = 111,111.11 or 111,111

Carrying cost = Carrying cost per zen-zen * (Order size / 2)
Carrying cost = $0.02 * (111,111 / 2)
Carrying cost = $1,111

The annual carrying cost for the zen-zens is $1,111

Answer 2.

Ordering cost = Ordering cost per order * Number of orders per year
Ordering cost = $501 * 36
Ordering cost = $18,036

The annual ordering cost for the zen-zens is $18,036

Answer 3.

EOQ = (2 * A * O / C)^(1/2)
EOQ = (2 * 4,000,000 * $501 / $0.02)^(1/2)
EOQ = 447,660.59 or 447,661

The optimal order quantity for the zen-zens is 447,661 zen-zens.

Answer 4.

Order size = 447,661

Number of orders per year = Annual sale / Order size
Number of orders per year = 4,000,000 / 447,661
Number of orders per year = 8.94 or 9 orders

Carrying cost = Carrying cost per zen-zen * (Order size / 2)
Carrying cost = $0.02 * (447,661 / 2)
Carrying cost = $4,477

Ordering cost = Ordering cost per order * Number of orders per year
Ordering cost = $501 * 9
Ordering cost = $4,509

Total inventory cost = Carrying cost + Ordering cost
Total inventory cost = $4,477 + $4,509
Total inventory cost = $8,986

At EOQ, the new total inventory cost will be $8,986
