Base on the question and the given values of the problem, I would say that the last payment would be to pay off a $1,250 computer plus 8% sales tax with monthly payment of $120 would be $12. I hope you are satisfied with my answer and feel free to ask for more if you have question and further clarification

1250x. 08 = 100+1250 = 1350 / 120 is 11.25 so 11 months of paying $120 leaves a $30 12th month payment.
