Given:

Amortization table is given

Let r be the annual rate of interest.

[tex]\frac{r}{12}\text{ be the monthly rate of interest.}[/tex]

Second payment:

P= $259873.20 ; interest = $539.24

[tex]\text{Interest for the 2nd payment = }P(\frac{r}{12}\times\frac{1}{100})[/tex][tex]539.24=259873.20(\frac{r}{1200})[/tex][tex]\frac{539.24}{259873.20}\times1200=r[/tex][tex]r=\frac{647088}{259873.20}[/tex][tex]r=2.49[/tex]

Therefore, the annula rate of interest is 2.49%
