Answer:
Step-by-step explanation:
D = 60 bags
cost = 80 / bag
s = 20 / order
h = 40% of cost
0.4 * 80 / 100
h= 32 unit/year
D = d * 12 months
D = 60 * 12
D = 720 bags / year
EOQ =
![√(2DS/H)](https://img.qammunity.org/2020/formulas/business/college/gz15n3525ias1vh46aishuzbg8p560zw89.png)
EOQ =
![√(2 *720*20/32)](https://img.qammunity.org/2020/formulas/business/college/3yls6wev42222lwbvta6onptwrcdwio43n.png)
EOQ = 30 bags
Total cost = Total holding cost + total ordering cost
Total holding cost = (Q/2 * H) = (30/2 * 32) = 480
Total ordering cost = (D/Q * 20) = (720/30 *20) = 480
Total cost = 480 + 480 = 960
Total purchasing cost = cost * D = 80 * 720 = 57.600
Percentage= total cost / total purchasing cost * 100
960 / 57.600 * 100
1.67 %
