Q: What is the future value of $1 after 6 years; if it incurs compound interest every year once.

Formula:
$FV = PV(1+\frac{r}{n})^{nt}$

where,
FV= Future Value
PV= Present Value = $1
r= interest rate = 8% = 0.08
n=frequency of interest application to the value per year = 1(if compunded annually); it means that 8% interest is applied only once a year.
t=time (in years)=6

$FV = PV(1+\frac{r}{n})^{nt}$
$FV = 1(1+\frac{0.08}{1})^{1*6}$
$FV = 1(1+0.08)^6$
$FV = (1.08)^6$

If 1$ were invested at 8% interest compounded annually, the total value of the investment at the end of 6 years would be:

Amount = P $(1+\frac{r}{100})^n$

P = Principal, r = rate of interest, n = number of years.
P = $1, r = 8% , n = 6 years

Amount = 1$(1+\frac{8}{100})^6$ = 1$(\frac{108}{100})^6$ = 1$(1.08)^6$ = $(1.08)^6$
Answer B...

D. 1 + (0.08)^6
E. 1 + 6(0.08)

Using the compound interest formula, we have:

future value = present value(1 + rate/n)^nt

(in which n = number of compounding periods in a year and t = total number of years)

future value = 1(1 + 0.08/1)^(1)(6)

future value = (1.08)^6

Answer: B

You can use this formula to calculate compound interest:
Final balance = P( 1 + r/c)^nc where:
P = the principal (the initial investment)
r = the annual interest rate expressed as a decimal
c = the number of times the interest is compounded each year
n = the number of years the investment collects interest

For this question, P = $1, r = 0.08, c = 1, n = 6
So, the FINAL BALANCE = 1( 1 + 0.08/1)^[(6)(1)]
= (1.08)^6
