NO.PZ2017102901000036问题如下In 2014, a company using US GAma cash payments of $6 million for salaries, $2 million for interest expense, an$4 million for income taxes. Aitioninformation for the company is proviin the table:Baseonly on the information given, the company’s operating cash flow for 2014 is closest to:A.$6 million.B.$10 million.C.$14 million. A is correct.Operating cash flows = Cash receivefrom customers – (Cash paito suppliers + Cash paito employees + Cash paifor other operating expenses +Cash paifor interest + Cash paifor income taxes)Cash receivefrom customers = Revenue + crease in accounts receivable= $37 + $3= $40 millionCash paito suppliers = Cost of goo sol+ Increase in inventory – crease in accounts payable= $16 + $4 + $2 = $22 millionTherefore, the company’s operating cash flow = $40 –$22 – Cash paifor salaries – Cash paifor interest – Cash paifor taxes = $40 –$22 – $6 – $2 –$4= $6 million. 老师，2014年的存货增加了4，根据公式资产项应该是减去，为什么答案是加上？

Purchase是20，但是公式前面有个负号啊？代入公式给suppliers 的钱就应该是-20+-2=-22啊最后40- -22-6-2-4老师我哪里错了谢谢
