Find the balance in an account with $7,000 principal earning 5% interest compounded quarterly

nadya68 [22]

Answer:

The balance is $\$11,505.34$

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

$t=10\ years\\ P=\$7,000\\ r=0.05\\n=4$

substitute in the formula above

$A=\$7,000(1+\frac{0.05}{4})^{4*10}=\$11,505.34$
