a,
marked price 減左30%之後變左 $1,400, so
marked price = 1400/(1-30%)
= $2,000
b.
間鋪頭用$1,400賣左件貨之後蝕左佢成本o既12.5%, so
cost = 1400/(1-12.5%)
= $1,600
marked price 減左30%之後變左 $1,400, so
marked price = 1400/(1-30%)
= $2,000
b.
間鋪頭用$1,400賣左件貨之後蝕左佢成本o既12.5%, so
cost = 1400/(1-12.5%)
= $1,600

(a)1400 除 (1-30%) =$2000
1400/(1-30%)=$2000
(b)2000乘(1-12.5%)=$1750
2000 x (1-12.5%)=1750

我宜家中3=.=你都唔岩,1400係售價,2000係標價即係買入數碼相機既錢,咁係2000到賣唔出2000就開始係虧蝕,so係2000乘(1-12.5%)=1750
1400/(1-30%)=$2000
(b)2000乘(1-12.5%)=$1750
2000 x (1-12.5%)=1750

1a) 1400 x 30%
= 42
b) 1400 x (1-12.5%-30%)
= 1400 x 57.5%
= $805
= 42
b) 1400 x (1-12.5%-30%)
= 1400 x 57.5%
= $805
