2.馬先生以$1200購入100本記事本.並以每本$20售出,求盈虧百分率。

✔ 最佳答案
1.盈虧百分率(210-150)/210 * 100%
=60/210 * 100%
=28 4/7%
2. 盈虧百分率
(20 * 100 - 1200) / 1200 * 60%
=800 / 1200 * 60%
=66 2/3%
3. 盈虧百分率
(1140 * 10 - 9500) / 9500 * 100%
=(11400-9500) / 9500 *100%
=1900 / 9500 * 100%
=20%
2007-04-19 23:09:13 補充：
1.盈虧百分率(210-150)/150 * 100%=60/150 * 100%=40%

=60/150x100%
=40%
2)20X100-1200/1200X100%
=800/1200X100%
=66又2/3%
3)1140x10-9500/9500x100%
=1900/9500X100%
=20%
希望我可以幫到你啦!

method : (new - old ) / old *100%
1. (210 -150) / 150*100%=40%
2. (100*20 - 1200 ) / 1200 *100% = 66.7% ( corr.to 3 sig. fig )
3. (10 *1140 - 9500 ) / 9500 *100% = 20%
I am sorry that I don't know how to write the formular in complete sentences
you' d better check the answer book.
