【答案解析】 本题需要掌握改变信用政策前后应收账款应计利息的计算,应收账款应计利息=日销售额×变动成本率×平均收现期×资本成本,根据题中给出的条件可以计算出改变信用政策前后应收账款应计利息的变动额。另外还需要计算出存货应计利息的变动及现金折扣成本的变动,最终就可以计算出改变信用政策前后的净损益,进而判断改变信用政策是否有利。 English answers: Increase of net gain after change of credit policy=108000+12240+7092-2880-86112=38340(Yuan) The company should implement the discount policy because the net gain is greater than0 after the change of credit policy.
