✔ 最佳答案
售價:6000x(1+15%)+1500x(1-35%)
=6000x115%+1500x65%
=6900+975
=7875(元)
原價:
6000+1500
=7500(元)
總盈利率:
( (7875-7500)/7500 )x100%
=5%

6000*115% = 6900
1500*65% = 975
(6900+975 / 6000+1500)*100 = 105
即是總盈利率是 5%
1500*65% = 975
(6900+975 / 6000+1500)*100 = 105
即是總盈利率是 5%

er................
I have write this que. but orz who don't know?
求梳化和茶几的總盈利率
=[6000*(1+15%)+1500*(1-35%)]-(6000+1500)
=(6900+975)-7500
=7875-7500
=375$
