on melissa's 6th birthday, she gets a $5000 CD that earns 3% interest, compounded semiannually. If the CD matures on her 10th birthday, how much money will be available?

Respuesta :

Answer:

[tex]\$5,632.46[/tex]  

Step-by-step explanation:

we know that    

The compound interest formula is equal to  

[tex]A=P(1+\frac{r}{n})^{nt}[/tex]  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

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  

[tex]t=10-6=4\ years\\ P=\$5,000\\ r=3\%=3/100=0.03\\n=2[/tex]  

substitute in the formula above  

[tex]A=5,000(1+\frac{0.03}{2})^{2*4}[/tex]  

[tex]A=5,000(1.015)^{8}[/tex]  

[tex]A=\$5,632.46[/tex]  

Answer:

The money available on her 10th birthday is $5627.54

Step-by-step explanation:

Given information:

Principal = $5000

Time = 4 years

Rate of interest = 3%

As we know that the formula for the amount of compound interest

[tex]A=P(1+\frac{r}{100})^n[/tex]

[tex]A=5000(1+\frac{3}{100})^4[/tex]

[tex]A=5000 \times 1.03^4\\A=5000 \times 1.125\\A=5627.54[/tex]

Hence, the money available on her 10th birthday is $5627.54
