The plan needs to be paid as: (200 20+40x) yuan;

Answer: When the customer buys 100 ties, the payment should be the same for both purchase plans (3) If the purchased tie is less than 100 ties, then it is more cost-effective to choose the plan;

If the purchased tie is equal to 100, then the choice of the scheme is the same cost-effective;

New York City, Neighborhood originated in '92, formerly known as Neighborhood NYC (New York City), and was originally sold in Union in Soho District. At that time, because the designer was an American, the design style was more inclined to militarized patterns and simple graffiti.

Although Neighborhood has not become a first-class big name in the United States, it has entered the entire Asian market since its debut, especially in Japan.

Neighborhood officially established its brand in Japan in 1994 (different from the American version of Neighborhood NYC). The copyright and design are handed over to Japanese designers, so there is also a bit of Japanese-style design on the graphic, and their intentions and characteristics can be seen in the simple font design.
