Given:
Present value, P=179500
interest per period (month), i = 0.0475/12
number of periods (month), n=30*12=360

Interest charged after first month
Interest=P*i
=179500*0.0475/12
=710.52

Monthly payment (just to confirm that A > Interest)
A = Pi(1+i)^n/((1+i)^n-1)
=179500*(0.0475/12)(1+0.0475/12)^360/((1+0.0475/12)^360-1)
= 936.36 (to the nearest cent.
>  710.52   so ok.
