一个发展商有一块临河的土地长X feet.这块土地要被分割成小块,每一小块长80 或100 feet.如果1/9的小块土地长80,剩余的40小块土地长100,问X为多少.
假设一共分成n块土地,(1-1/9)n=40,so n=45,80*5+100*40=4400.
D

一个开发者有一块土地，这个土地有X尺的宽（朝向lake的那一面的长度）。这块土地要被分成若干个小条。每一个小条的宽必需是80或100尺。
现在有九分之一的条宽80
有40个条宽100
问X的值是多少？
假设一共有Y个条
有九分之八的 条宽100
九分之八*Y =40
Y=40除以九分之八。
Y=45
X=5*80 + 40*1...
