THE FOLLOWING INFORMATION APPLIES TO QUESTIONS 6 TO 9:

Short Grass Incorporated is a distributor of golf balls. Martin’s Golf Supplies is a local retail outlet which

sells golf balls. Martin’s purchases the golf balls from Short Grass Incorporated at $0.75 per ball; the golf

balls are shipped in cartons of 72. Short Grass Incorporated pays all incoming freight, and Martin’s Golf

Supplies does not inspect the balls due to Short Grass’ reputation for high quality. Annual demand is

155,520 golf balls. Martin’s Golf Supplies earns 12% on its cash investments. The purchase-order lead

time is one month. The following costs data are available:

Relevant ordering costs per purchase order

$125.00

Carrying costs per carton per year:

relevant total

costs

?

a.

$1,500

b.

$652.50

c.

$2,152.50

d.

$3,000

Order Quantity = Annual Demand/12

= 155,520÷12

= 12,960 golf balls per month

= 12,960 ÷72

=

180 carton

per month

RTC = Ordering Costs + Carrying Costs

Carrying Costs per carton = [$0.77 + ($0.75 x 72 x 12%)] = $0.77 + 6.480=

$7.25

Relevant Total Costs

= [Number of Orders x Ordering Costs] + [Average Inventory x CC per carton

= (12 x $125) + [(180/2) x $7.25]

= $ 1,500 + $652.50

=

$2,152.50
