____ is the amount of a $3,000.00 annuity due at 12 percent compounded semiannually for 3 years
ANEK [815]
The formula of the present value of annuity due:
PV=C*[\frac{1-(1+i)^{-n}}{i}]*(1+i)

For your case:
C = $3000
i = 12% / 100 = 0.12
n = 3 * 2 = 6 (semiannually for 3 years means 6 payments)

So, the solution is:
PV=3000*[\frac{1-(1+0.12)^{-6}}{0.12}]*(1+0.12)=3000*[\frac{1-0.5066}{0.12}]*1.12=
=3000*[\frac{1-0.5066}{0.12}]*1.12=3000*4.1114*1.12=13814.32

Beth will borrow $10,000 which earns 4% compound interest and she will repay that amount in 20 years. How much interest was earn
Serggg [28]

Answer:

I=\$11,911.23

Step-by-step explanation:

we know that    

The compound interest formula is equal to  

A=P(1+\frac{r}{n})^{nt}  

where  

A is the amount that she will repay  

P is the amount borrowed  

r is the rate of interest  in decimal

t is Number of Time Periods  

n is the number of times interest is compounded per year

in this problem we have  

t=20\ years\\ P=\$10,000\\ r=0.04\\n=1  

substitute in the formula above  

A=10,000(1+\frac{0.04}{1})^{1*20}  

A=10,000(1.04)^{20}  

A=\$21,911.23  

Find out the interest

I=A-P

substitute the values

I=\$21,911.23-\$10,000=\$11,911.23
