Komok [63]

Answer:

$A=\$6,768.75$

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

$t=10\ years\\ P=\$5,600\\ r=0.019\\n=4$

substitute in the formula above

$A=\$5,600(1+\frac{0.019}{4})^{4*10}$

$A=\$5,600(1.00475)^{40}=\$6,768.75$
