Q14:
$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
答案D.
我人为是C. 因为题目问的是 the deposit 再3 三年后会是多少? D(t)(1+r/100)^3=? ,needs to know D(t) and r
1.10000(1+r/100)^t=D(t)=11000; r,t unknown
2.r=10; t unknown,then D(t) can't be computed
1and2 combine , then got the answer,
