✔ 最佳答案
1. The price of the pen,$1200(1-20%) ←1支筆比原本既售價平左20%,所以減
=$1200(80%)
=$960
2. $10000(5%)(t) = $1500 ←有條formula
t = 1500 / (10000 x 0.05)
t = 1500/500
t =3

1.)一枝筆的售價
=1200*(1-20%)
=1200*80%
=$960
2.)10000*t*5%=1500
500*t=1500
t=1500/500
=3
∴t的值是3
=1200*(1-20%)
=1200*80%
=$960
2.)10000*t*5%=1500
500*t=1500
t=1500/500
=3
∴t的值是3

1.
1200-(1200x20%)
=1200-240
=960(元)//
2.
1500÷(10000x5%)
=1500÷500
=3(年)//
t=3//
1200-(1200x20%)
=1200-240
=960(元)//
2.
1500÷(10000x5%)
=1500÷500

1. 售價：1200乘(1-20%)
=1200x80%
=1200/100x80
=12x80
=$960
2. t的值：
10000x(5%)(t)=1500
t=1500/(10000x5%)
t=1500/500
t=3
=1200x80%
=1200/100x80
=12x80
=$960
2. t的值：
10000x(5%)(t)=1500
t=1500/(10000x5%)
t=1500/500
t=3
2007-01-25 6:11 am
1. 售價 = $1200 x (100-20)% = 1200 x 0.8 = $960
2. $10000 x 5% x t = $1500
t = 1500 / (10000 x 0.05)
t = 3年
2. $10000 x 5% x t = $1500
t = 1500 / (10000 x 0.05)
t = 3年
