Answer:
$3,700
Explanation:
total annual demand = 500 x 50 = 25,000
if 200 units are purchased at a time, then they need to make 25,000 / 200 = 125 orders per year.
annual ordering costs = 125 x $20 = $2,500
average inventory = 200 / 2 = 100
annual holding cost = 100 x $40 x 30% = $1,200
total = $2,500 + $1,200 = $3,700
