Answer
Solution: B
Let [math]K[/math] be annual payment. Here [math]v=(1+i)^{-1}=8 / 9[/math]. Then [math]153.60=I_n=K(1-v)=K / 9[/math] so [math]K=153.86(9)[/math]. Next [math]P R_n=K-I_n=9(153.86)-153.86=8(153.86)[/math]. Then [math]X=\sum_{i=1}^n P R_i=P R_n+6009.12=[/math] [math]8(153.86)+6009.12[/math]
Thus [math]Y=K-X i=9(153.86)-[8(153.86)+6009.12(9)](1 / 8)=479.6235[/math].
