進度表:
1. 清空:大理石茶几、電視櫃、沙發、吊掛喇叭、及其他細軟零散家具擺設。
2. 系統:4.5*10+3*4=76;櫃留:76-16=60
[源 - 三下養 - 養下硝 - (硝上雨缸 - 缸溢下硝...) - 排]...
3. 試算:
D:(1st y)
systm = 500k
60*100 = 6000 = 1000 + 200*20*1.25 (0.5y full) = 50k
ub = 30*6 = 180k
pc = 15*12 = 180k
msln = 40k
-----------------------------------------------------------------
ttl: 950-1000k
D:(after 1st y)
ub = 30*6 = 180k
pc = 15*12 = 180k
msln = 40k
-----------------------
ttl: 400k
//////////////////////////////////////////////////////////////////
C:(1st y)
60*300*30*2 = 1080k (76-60 = 280k/0.5y)
C-D = 100k±30k
----------------------------------------------
C:(after 1st y)
60*300*30*4 = 2160k (76-60 = 570k/y)
C-D = 1760k
