章节大纲
-
To practice a number of different topics covered in this chapter, from plotting points to determining slope, explore the following situation:
::将本章涵盖的若干不同专题付诸实践,从绘图点到确定坡度,探讨以下情形:You have designed a new invention, and you're doing some analysis of cost and expenses. You're currently making about $65,000 per year, but you are hoping your new invention will allow you to double your salary .
::你设计了一个新的发明,你正在对成本和开支做一些分析。你目前每年赚大约65,000美元, 但你希望你的新发明能让你的薪水翻一番。You have found that you have to make an initial investment in supplies, plus a certain amount per unit produced. The cost to make 40 units is $10,000, and the cost to make 100 units is $20,500. Your market research also tells you that your price point should be $250 per unit.
::您发现,您必须首先在供应品上投资, 加上每生产一个单位的一定数量。 生产40个单位的成本是10,000美元,生产100个单位的成本是20,500美元。 您的市场研究还告诉您, 您的价格点应该是每生产250美元。Directions:
