$\$1,616.60$

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

in this problem we have

$t=5\ years\\ P=\$1,500\\ r=1.5\%=1.5/100=0.015\\n=4$

substitute in the formula above

$A=1,500(1+\frac{0.015}{4})^{4*5}$

$A=1,500(1.00375)^{20}$

$A=\$1,616.60$
