**drwls**, Monday, January 11, 2010 at 11:54amThe original unpaid balance was

P = 0.8 x 995 = $796.00

A finance charge of 19.4% is 19.4%/12 = i = 1.61667% per month. The number of payments is n = 18

The formula you need to use can be found at

It is

A = P i /[1 - (1+i)^-n]

In your case,

A = 796*.0161667/[1 - 0.74929] = $51.32
