问题 解答题

某商场计划投入一笔资金购买一批紧俏商品,经过市场调查有两种出售方式可供选择.

方式一:如果月初出售,则可获利15%,并可用本和利再投资其他商品,到月末又可获利10%,另付仓储费500元;

方式二:如果月末出售,则可获利30%,但要付仓储费700元.

(1)若商场投入x元,请写出这两种方式的获利情况;

(2)若商场准备投入3000元,你认为哪种方式较好?

答案

(1)方式一获利:(15%+1)(1+1多%)x-5多多-x=(多.265x-5多多)(元),

方式九获利:(3多%x-地多多)(元).

(2)当x=3多多多元时

方式一获利为:(多.265x-5多多)=多.265×3多多多-5多多=295(元);

方式九获利为:3多%x-地多多=3多%×3多多多-地多多=2多多(元);

因为295>2多多,所以若投入3多多多元时,方式一较好.
