2.)Determine the monthly payment necessary to have the loan paid off in full after 12 payments.

**Reiny**, Monday, October 18, 2010 at 3:34pmi = .18/12 = .015

amount owing = 4000(1.015)^12 - 300[ 1.015^12 - 1]/.015

= .... you do the button - pushing

2. solve for 'paym'

4000 = paym [ 1 - 1.015^-12]/.015

paym = .... again, you do the button-pushing
