问题解答题

某服装厂现有甲种布料42米，乙种布料30米．现计划用这两种布料生产M，N两种型号的校服共40件，已知做一件M型号的校服需要用甲种布料0.8米，乙种布料1.1米．做一件N型号的校服需用甲种布料1.2米，乙种布料0.5米，按要求生产M，N两种型号的校服，有哪几种生产方案？请你设计出来．

答案

设要做x件N型号的校服，则需做（40-x）件M型号的校服，

由题意得：

0.8(40-x)+1.2x≤42

1.1(40-x)+0.5x≤30

，解得：23

1

3

≤x≤25．

所以有两种方案．

方案一：生产M型号的校服15件，N型号的校服25件；

方案二：生产M型号的校服16件，N型号的校服24件．
