✔ 最佳答案

Let y be the marked price of the refrigerator, then
y * 23%=1150
y=5000

So the selling price of the refrigerator is:
$5000-$1150=$3850

市場價為$5000, 實際售價為$3850, 比市場價少$1150, 亦即是市場價的23%, 這樣才符合題意.

所以答案5才是正確的.

題目是問實際售價 Selling Price, 答案1-4都只是算出了市場價 (標價 Marked Price) $5000, 所以不對.

Let y be the selling price of the refrigerator.

23%y= 1150
y =1150 x 100/23
y= 5000

The selling price of the refrigerator is $5000 .
