At the beginning of year 1, Josie invests $400 at an annual compound interest

zvonat [6]

Answer:

The explicit formula that can be used is $A=\$400(1.05)^{2}$

The account's balance at the beginning of year 3 is $A=\$441$

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

$t=2\ years\\ P=\$400\\ r=0.05\\n=1$

substitute in the formula above

$A=\$400(1+\frac{0.05}{1})^{1*2}$

$A=\$400(1.05)^{2}$

$A=\$441$
