Can someone walk me through how I would enter this into the calculator TMV solver. Can it be done?
Jeremy has a balance owing of $4000 on his credit card. The creditcard company charges 18.0% annual interest, compounded monthly.
1.) If Jeremy makes payments of $300 every month, how much will he still owe after making 12 payments?
2.)Determine the monthly payment necessary to have the loan paid off in full after 12 payments.

i = .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 buttonpushing
