Re: [問題] 請各位幫幫我的忙
※ 引述《chsh410862 (靈活的胖子)》之銘言：
: 在做微積分考古題時有這兩題需要請各位幫幫忙
: A motorcycle shop estimates that it well sell 750 motorbikes in a year.
: Each bike cost$300,plus a fixed charge of$400 per order. If it costs $240
: to store a motorbike for a year,what is the order size and how orders will
: be needed in a year to minimize inventory costs?
: 有點不懂題意
: 這個類似題型每年都會出
: (至少幫忙翻譯一下orz)
: A sum is invested at 15% compounded continuously.How long will it triple?
: (ln3=1.0986)
: 只給ln3?
: 帥哥高手們一定要幫幫醜男我啊orz
有一間賣機車的店預估一年能夠賣出750臺機車，而每一臺機車要價$300
且每次進貨會有一個固定的$400的費用。而每一臺機車每年的倉儲成本為
$240。則請問在一年之中，應該要進幾次貨，而每次進貨進多少臺機車
才能夠讓一年的倉儲成本最低?
PS. 就我所知...基本上inventory cost通常是累計且連續的 所以一個月可以是$20
應該是這樣翻沒錯 看有沒有幫助 @"@
然後第二題他有說是compounded continuously
所以應該是要用永續年金的觀念下去做我猜
