a)    p =  - 1 = 0.006638834
   n =   =   =   = 245.8378879
   246 payments

b)    PVn = 1140.00  = 1140.00(.8293897) = $949.40
   949.40(1.006638834) = $955.70

c)   137960.70 = PMT    
   137960.70 = PMT(87.73874749)    
   $1572.40 = PMT    
   Contractual = 1572.40(132)    =   $207 556.80
   Actual = 1140.00(245) + 955.70   =   280 255.70
   Difference in payments    =   $72 698.90
