Say you have $14,000 to invest into an investment account. You can either invest your money into an account with a 7% annual int
taurus [48]

Answer:

You should choose an account with a 7% annual interest rate which is compounded quarterly

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 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

part 1)

we have  

t=15\ years\\ P=\$14,000\\ r=0.07\\n=4  

substitute in the formula above  

A=14,000(1+\frac{0.07}{4})^{4*15}

A=14,000(1.0175)^{60}  

A=\$39,645.43  

part 2)

we have  

t=15\ years\\ P=\$14,000\\ r=0.068\\n=12  

substitute in the formula above  

A=14,000(1+\frac{0.068}{12})^{12*15}

A=14,000(1.0057)^{180}  

A=\$38,713.11
