$10,000 is deposited in a certain account that pays r percent annual interest compounded annually, the amount D(t), in dollars, that the deposit will grow to in t years is given by D(t) = 10,000 {1+(r/100)}t. What amount will the deposit grow to in 3 years?
(1) D(t) = 11,000
(2) r =10
此题选D.
1之所以可以,是不是因为D已经限定死了D(t)=11000,也就是r一定不是10了.
这样以来,不是1和2推出3年后的deposit不一样了.
在目前的DS题目中,似乎还没有1和2都能推出答案,但答案却不同的吧!
哪个NN过来看看呢?
这道题本身有问题吧,请问lz出处在哪?
