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.
看清问题，为什么期数减半，利润会下降？
而不是，为什么不能达到利润最大化，利润上升的目的
A a typical issue 每一期邮费增加1/3→4/3 ✖ 期数减半 1/2 ＝2/3 邮费减少，利润应该上升
D spend the same amount on advertising per issue 注意per issue 广告商每一期给的广告费不变，期数减半，那么广告费减半，收入下降，利润下降，√
E 错选，以为公司想要减少期数是因为 期数少了，总的生产成本可以下降，就能maximum profit。错看问题，以为问的是为什么不能达到maximum profit 利润上升的目标。 因为看到E说生产成本不变，就觉得通过减少期数来增加利润不能实现。
注意问的是利润减少 加强
