Question 1102295: An initial investment of $21,500 is placed in a bank account that earns 3.92% interest, compounded annually. At the end of 6 yrs the money is withdrawn from the bank. The function A(t)=21,500(1.0392)^t models the value of the investment. The variable t represents the length of the investment in years. What is the reasonable domain for the function given this situation?
A. any rational number t, such that 0≤t≤3.92
B. any whole number t, such that 21,500≤t≤27,079
C. any whole number t, such that 0≤t≤6
D. any rational number t, such that 3.92≤t≤6
