To fill an order on schedule, a manufacturer had to produce 1,000 tools
per day for n days. What is the value of n ?
(1) Because of production problems, the manufacturer produced only 600
tools per day during the first 5 days.
(2) Because of production problems, the manufacturer had to produce 1,500
tools per day on each of the last 4 days in order to meet the schedule.
这题的答案是E 但我想问C
我的想法是 (1) (2) 结合的话
1000n =600*5+1500*4+1000(n-4-5)
就总共的N天数扣掉前面跟後面有状况的天数後一样是每天1000
因此可得出唯一解 我实在想了很久不知到哪边鬼遮眼了
在麻烦大家了 谢谢!!

1F：推 LittleRiver: 你的算式是恒等式喔 还是无法得到n 12/22 12:27
2F：→ LittleRiver: 而且他没有说除了这4天或5天外 剩下的每天做1000 12/22 12:29
3F：推 reko076: (1)(2)讲的是同一件事情，前面五天共落後2000件，後面赶 12/22 14:40
4F：→ reko076: 工每天多作500件要四天才能追上进度。两条件相加只能知道 12/22 14:40
5F：→ reko076: n是大於等於9的正整数 12/22 14:40
