Solution:
The purchaser contacted HDT to accept their commitment for FAS Doha, but demanded that if the selling terms of the FOB HDT Crown HDT plant had changed they be deducted from $172,000 per truck price.
The terms and conditions were created.
As the point of sale moved from Doha to Crown Point, the customer must carry on all expenses to bring the goods to the port.
Since I don't know the cost of labour and supplies,
I assume it will cost around $2.746 per truck because that's how much they spent on transporting them from the port of Baltimore to Doha.
