Answer:
The optimal stocking level is 45 muffins.
Step-by-step explanation:
First we have to calculate the Overage cost Co = Purchase price - Salvage value = $0.2 - 0 = $0.2
Then the Underage cost Cu = Selling price - Purchase price =$0.80 - $0.2 = $0.60
Service level = Cu / (Cu + Co) = $0.60/($0.60+$0.2) = $0.75
Hence, optimal stocking level = Minimum demand + Service level *(Maximum demand - Minimum demand)
optimal stocking level = 30 + 0.75*(50-30) = 45
The optimal stocking level is 45 muffins.
Optimal stocking level = 68.75 Muffins
