Find the balance in the account. $2,400 principal earning 2%, compounded annually, after 7 years $307,200.00 $17,136.00 $2,736.0

Lisa [10]

Answer:

$2,756.85$

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

$t=7\ years\\ P=\$2,400\\ r=2\%=2/100=0.02\\n=1$

substitute in the formula above

$A=2,400(1+\frac{0.02}{1})^{1*7}$

$A=2,400(1.02)^{7}$

$A=2,756.85$
