推 LittleRiver: 你的算式是恆等式喔 還是無法得到n 12/22 12:27
→ LittleRiver: 而且他沒有說除了這4天或5天外 剩下的每天做1000 12/22 12:29
推 reko076: (1)(2)講的是同一件事情，前面五天共落後2000件，後面趕 12/22 14:40
→ reko076: 工每天多作500件要四天才能追上進度。兩條件相加只能知道 12/22 14:40
→ reko076: n是大於等於9的正整數 12/22 14:40
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.
這題的答案是E 但我想問C
我的想法是 (1) (2) 結合的話
1000n =600*5+1500*4+1000(n-4-5)
就總共的N天數扣掉前面跟後面有狀況的天數後一樣是每天1000
因此可得出唯一解 我實在想了很久不知到哪邊鬼遮眼了
在麻煩大家了 謝謝!!
