Answer:
The correct answer is letter "B": Accept the USA distributor demand. It is even better for Tetsu compared to Japan.
Step-by-step explanation:
Considering both the distributors in Japan and the U.S. request a 20% margin for the retails of Tetsu's devices, accepting the offer of the U.S. company represents a good deal. Businesses are not handled the same in Japan and the U.S. Both countries have different policies. Tetsu must consider that the U.S. is a bigger market and that its devices are imported in the U.S., implying there could be tariffs imposed. Tough, if the U.S. distributor requests the same margin a Japanese distributor does to start businesses, the deal will be in Tetsu's favor.
