銷貨毛利率=銷貨毛利/銷貨淨額
30%=45,000/銷貨淨額
銷貨淨額=150,000
銷貨成本=銷貨淨額-銷貨毛利
銷貨成本=150,000-45,000=105,000
銷貨毛利率=銷貨毛利/銷貨淨額
30%=45,000/銷貨淨額
=>銷貨淨額=150,000
方法1
銷貨毛利率+銷貨成本率=1
銷貨成本率=1-30%=70%
銷貨成本率=銷貨成本/銷貨淨額
70%=銷貨成本/150,000
=>銷貨成本=105,000
方法2
銷貨淨額-銷貨成本=銷貨毛利
150,000-銷貨成本=45,000
=>銷貨成本=105,000
毛利率+成本率=1
30%>45000
100%>150000
成本率=70%
150000x70%=105000
銷貨毛利率+銷貨成本率=1
銷貨成本率=1-0.3=0.7
銷貨淨額:45,000/0.3=150,000
銷貨成本:150,000*0.7=105,000
45000/0.3=150000
150000*0.7=105000
