问题 解答题
漳州三宝之一“水仙花”畅销全球,某花农要将规格相同的800件水仙花运往A,B,C三地销售,要求运往C地的件数是运往A地件数的3倍,各地的运费如下表所示:
 
A地
B地
C地
运费(元/件)
20
10
15
(1)设运往A地的水仙花x(件),总运费为y(元),试写出y与x的函数关系式;
(2)若总运费不超过12000元,最多可运往A地的水仙花多少件?
答案

(1)y=25x+8000   (2)160件

(1)根据总运费=运往A地的费用+运往B地的费用+运往C地的费用,由条件就可以列出解析式;

(2)根据(1)的解析式建立不等式就可以求出结论.

解:(1)由运往A地的水仙花x(件),则运往C地3x件,运往B地(800-4x)件,由题意得

y=20x+10(800-4x)+45x,

y=25x+8000

(2)∵y≤12000,

∴25x+8000≤12000,

解得:x≤160

∴总运费不超过12000元,最多可运往A地的水仙花160件.
