练习题如下：

 

cash received from sale of buidling $40

purchase of machinery $20

profit on sales of building $20

, 计算investing cashflow.

 

答案：investing cashflow =

cash received from sale of buidling $40-purchase of machinery $20 =20

 

 

我不明白 为什么 PROFIT ON SALES OF BUILDING 不加入 investing cashflow 的计算中？
