A fresh produce distributor uses 770 non-returnable packing crates a month, which it purchases at a cost of $6 each. The manager has assigned an annual holding cost of 28 percent of the purchase price per crate. Ordering cost is $32 per order. Currently the manager orders 770 crates at a time. How much could the firm save annually in ordering and holding costs by using the EOQ? (Round the final answer to 2 decimal places.) |

Please find below Answer to question 1 :
Following are the relevant data :
Annual demand of crates = D = 770 / MONTH X 12 MONTHS = 9240 CRATES
Ordering cost = Co = $32
Annual unit holding cost = Ch = 28 percent of $ 6 = 0.28 x 6 = $1.68
Therefore ,
Economic Order quantity ( EOQ )
= Square root ( 2 x Co x D / Ch )
= Square root ( 2 x 32 x 9240 /1.68 )
= 593.29 ( 593 crates rounded to nearest whole number )
At order quantity = 593 crates :
Annual ordering cost
= Ordering cost x Number of orders
= Ordering cost x Annual demand/ Order quantity
= Co x D/ EOQ
= $32 x 9240 / 593
=$498.62
Annual inventory holding cost
= Annual unit inventory holding cost x Average inventory
= Ch x EOQ/ 2
= $1.68 x 593/ 2
= $498.12
Therefore .
Total annual ordering plus inventory holding cost = $498.62 + $498.12 = $996.74
At order quantity = 770 crates:
Annual ordering cost
= Ordering cost x Number of orders
= Ordering cost x Annual demand/ Order quantity
= Co x D/ order quantity
= $32 x 9240 / 770
=$384
Annual inventory holding cost
= Annual unit inventory holding cost x Average inventory
= Ch x Order quantity / 2
= $1.68 x 770/2
= $ 646.80
Therefore .
Total annual ordering plus inventory holding cost = $384 + $646.80 = $1030.80
Therefore amount the firm saves annually in ordering and inventory holding cost
= $1030.80 - $996.74
= $34.06
