Answer:

[tex]\$2,369.11[/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  

Part 1)

[tex]t=2\ years\\ P=\$2,000\\ r=0.04\\n=12[/tex]  

substitute in the formula above

[tex]A=2,000(1+\frac{0.04}{12})^{12*2}[/tex]  

[tex]A=2,000(1.0033)^{24}[/tex]  

[tex]A=\$2,166.29[/tex]  

Part 2)

[tex]t=2\ years\\ P=\$2,166.29\\ r=0.045\\n=4[/tex]  

substitute in the formula above

[tex]A=2,166.29(1+\frac{0.045}{4})^{4*2}[/tex]  

[tex]A=2,166.29(1.01125)^{8}[/tex]  

[tex]A=\$2,369.11[/tex]
