Because postage rates are rising, Home Decorator magazine plans to maximize its profits by reducing by one half the number of issues it publishes each year. The quality of articles, the number of articles published per year, and the subscription price will not change. Market research shows that neither subscribers nor advertisers will be lost if the magazine's plan is instituted.
Which of the following, if true, provides the strongest evidence that the magazine's profits are likely to decline if the plan is instituted?
With the new postage rates, a typical issue under the proposed plan would cost about one-third more to mail than a typical current issue would.
The majority of the magazine's subscribers are less concerned about a possible reduction in the quantity of the magazine's articles than about a possible loss of the current high quality of its articles.
Many of the magazine's long-time subscribers would continue their subscriptions even if the subscription price were increased.
Most of the advertisers that purchase advertising space in the magazine will continue to spend the same amount on advertising per issue as they have in the past.
Production costs for the magazine are expected to remain stable.
前面几个评论的瞎扯吧 成本下降利润就增加？ 利润=收入-成本， 成本下降的同时，收入也下降，收入下降的比成本大，所谓的让利润最大化，是指利润如何减少的最少 。
利润=发行杂志数量*（单价-单本邮费+单本广告收入）
A选项之告诉我们邮费增加，但是广告收入如果增加 有可能使最后的利润增加
D选项 让唯一一个没有提到的变量固定 从而利润不会增加
