Answer:
Economic Production Quantity = 233.55 boxes per month =234 Boxes
Step-by-step explanation:
EPQ =
![\sqrt{(2KD)/(h(1-x)) }](https://img.qammunity.org/2021/formulas/business/college/o95nipz9ja6khbjcn3si7qferasbhzlwa4.png)
K= Set up cost = $60
D =Demand rate = 400
H= holding cost = $2
x= Demand Rate / Production Rate = 400/ (36*20) =0.56
substitute values into formula
EPQ =
![\sqrt{(2*60*400)/(2(1-0.56)) }](https://img.qammunity.org/2021/formulas/business/college/mlbc11v5q8p9u69w2rkexakaw5c6jxtr78.png)
= 233.55 Boxes per month
