Can you please help me? I know this question has been posted a lot before, but the answers are wrong...

A company in Hungary manufactures and sell the product "Mini Bike". The company operates at maximum capacity, producing seven days a week, which makes 50 000 units per year. (To make it simple, we assume that a year has 50 weeks.)

The value of a Mini Bike unit leaving production is 100. The cost of capital is estimated to 20%. The cost for holding inventory is 15%, which gives a total inventory carrying cost percentage of 35%. No safety stock is kept in Hungary.

Mini Bike is distributed to a wholesaler in the UK, where it's sold to the end customers. There are two transportation alternatives - by rail or by truck:

• By rail means a dispatch every 14 days. The transportation time is one week. The cost is 4/unit.
• By truck means a dispatch every week. The transportation time is two days. The cost is 6/unit.

In the UK, the wholesaler has a safety stock corresponding to half a week of sales.

Which distribution alternative gives the lowest total cost when considering the transportation cost and inventory carrying cost, in Hungary, during transportation and in the UK?
