Deposit ¥5000 in a bank for 2 years...
Deposit ¥5000 in a bank for 2 years with interest rate 4% p.a.What is the interest?What is the amount?
___(principal)x___(interest rate)___(time)=___(interest)
___(principal)x___(interest)=___(amount)
▼优质解答
答案和解析
5000x4%x2=400
5000+400=5400
按照4%的年利率,把5000元存入银行两年,利息是多少?总额是多少?
5000 (principal本金)x 4%(interest rate 利率)x2 (time 存期)=400 (interest 利息)
5000 (principal)+ 400 (interest)=5400 (amount 总额)
公式有两处错误,1.time前面少个乘号; 2.是+,不是x
另外这算法也不对呀,第一年的利息在第二年里没计算利息.
