Answer:

Bank B would pay more interest than Bank A by $0.40

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  

Bank A

[tex]t=1\ years\\ P=\$1,000\\ r=0.07\\n=4[/tex]  

substitute in the formula above  

[tex]A=1,000(1+\frac{0.07}{4})^{4*1}[/tex]  

[tex]A=1,000(1.0175)^{4}[/tex]  

[tex]A=\$1,071.86[/tex]  

Bank B

[tex]t=1\ years\\ P=\$1,000\\ r=0.071\\n=2[/tex]  

substitute in the formula above  

[tex]A=1,000(1+\frac{0.071}{2})^{2*1}[/tex]  

[tex]A=1,000(1.0355)^{2}[/tex]  

[tex]A=\$1,072.26[/tex]  

Find out the difference

[tex]\$1,072.26-\$1,071.86=\$0.40[/tex]

therefore

Bank B would pay more interest than Bank A by $0.40
