✔ 最佳答案
a)selling price=320*(1-30%)=$224b)(320*70%)*48%=cost price
cost price=$107.52
profit per cent=(224-107.52)/224*100%=52%

a) Selling price
$320 x 70% = $224
b) Profit per cent
$320 x 30% = 48% (Cost price)
Cost price = ($320 x 30%) / 48% = $200
Profit per cent = (($224 - $200) / 200) x 100% = 12%
$320 x 70% = $224
b) Profit per cent
$320 x 30% = 48% (Cost price)
Cost price = ($320 x 30%) / 48% = $200
Profit per cent = (($224 - $200) / 200) x 100% = 12%
