问题如下：

The amount of cash Sweetfall Inc. paid to suppliers is
选项：
A.$25,700.00 B.$26,702.00 C.$27,826.00解释：
SolutionA is correct. The amount of cash paid to suppliers is calculated as follows:
= Cost of goods sold – Decrease in inventory – Increase in accounts payable
= $27,264 – $501 – $1,063
= $25,700.
这两道题的“depreciation"都是前面没有负号，为什么这道题目，就可以直接用学习到的公式 -▲inv-COGS+▲AP来计算
但是NO.PZ2019120301000104题目中，老师的解答说，因为“depreciation"都前面没有负号，所以要用间接什么法来解释，正负号就都变了，就不能用这个上面的公式了
