Answer 1

英语水平不行啊，见笑见笑，尽力而为。
一个公司生产一种玩具。这种玩具，每个消耗可变成本12.30美元，固定成本98000美元。这种玩具每个卖17.98美元。设X为玩具生产和卖出的数量。
a）这个公司总的生产成本是总的可变成本加固定成本。已知总的生产成本为C，计算玩具的生产数量。
b）已知收入为R，计算玩具的销售量。
c）已知利润为P，计算玩具的销售量。注意：（利润=收入-总成本）

解：a）X=(C-98000)/12.30
b）X=R/17.98
c）(17.98-12.30)*X-98000=P ; X=P+98000/(17.98-12.30)

Answer 2

The total cost C equivalent 12.30X+98000.
The revenue R equivalent 17.98X.
The profit P equivalent 5.68X-98000.
