问题如下：
Golden Cumulus Corp., a commodities trading company, reported interest expense of $19 million and taxes of $6 million. Interest payable increased by $3 million, and taxes payable decreased by $4 million over the period. How much cash did the company pay for interest and taxes?
选项：
A.$16 million for interest and $10 million for taxes.
B.$16 million for interest and $2 million for taxes.
C.$22 million for interest and $10 million for taxes.
解释：
A is correct.
cash interest= -interest expense + △ interest payable = -19+3= -16
cash taxes= - income tax expenses + △tax payable = -6 + (-4)= -10
这题可能换过了答案都不是解释这个的。这个int和tax.为什么算法不一定呢
