Answer:
60 Kits
Step-by-step explanation:
Cost price (C) = $20/Kit
Yearly se (D) = 250 kit/year
Shipping cost / Ordering cost (Co) = $25
Holding cost (Ch) = $3.5/Kit-year
Economic order quantity = √2.D.Co / Ch
Economic order quantity = √2*250*25/3.5
Economic order quantity = √12500/3.5
Economic order quantity = √3571.4285
Economic order quantity = 59.7614305
Economic order quantity = 60 Kits
