Pavel [41]

Answer:

Given that,

An amount of $23,000 is borrowed for 11 years at 6.75% interest, compounded annually.

To find the Amount paid back after 11 years.

Explanation:

we know that,

The formula to find the,

Amount after n years of interest rate r% compounded annually is,

$A=P(1+\frac{r}{100})^n$

where P is the initial amount.

Here, we have that,

P=$23,000

r=6.75

n=11

Substitute the values we get,

$A=23000(1+\frac{6.75}{100})^{11}$

Solving this we get,

$A=23000(1+0.0675)^{11}$ $A=23000(1.0675)^{11}$ $A=23000(2.05138)$ $A=47181.805$

Round to the nearest dollar.

$A=47181.805\approx47182$

Answer is: Amount paid back is $47182 after 11 years
